It settles almost nothing. If you go look at a factory bike, anything modern to in the last 15+ years. Take the factory paper filter out and get a Sprint air filter (mind you this is a TRACK only filter and actually filters almost nothing) and you will in fact gain horse power, that you can measure on a dyno. Chris Moore at Moore Mafia has videos up showing it. However, as I mentioned, they filter near on nothing, so naturally, its highly ill advised to daily drive/ride something with a filter like this, and may even be illegal in some places.

Mainline dyno’s have definitely thrown us as a part manufacturer for a loop in the past. They’re very strict in some ways, and definitely could be the problem. It would have been useful to do the test in the same day. But given the location of that filter and the way a dyno operates I suspect the intake air temp has significantly changed, which can not only result in natural performance loss but also can trigger the calibration to significantly lower power in order to avoid knock.
You can only do so many mods before you get into needing tuning, and I feel you guys are right there at the door.

Yes! Plus I'm pretty sure the dyno works by knowing torque and doing maths to give a power figure. Bigger wheels = less torque = less power number on dyno, even if engine horsepower increased.
I'm a mechanical engineer who worked (past tense) in the automotive aftermarket, so I might have some insight. Here's how it probably went. A salesman or reseller somewhere told the K&N engineering team that they needed an intake kit for the Swift to fill out the K&N sales catalog, but the engineering team were probably given little (or no) access to an actual Suzuki Swift for testing, so they gave it a good guess, created a kit using parts that K&N already had, and were forced to move on to the next project.

As someone working in RnD, this is pretty accurate on how most of the engineering is done in big companies. Not for all products but certainly Swift's kit is an example. Add on top of that misunderstood engineering notes that get overpromised by the marketing and sales. Another case might be that they know it loses power but that wouldn't make sense for a product so they will look for a corner case or additional modifications to justify this filter.
Im in the uk and i used to like induction filters for the noise when i was younger, but since i've got a bit older and a bit smarter, now i keep the standard air box, chop any fins inside the box to make it as smooth as possible, replace the ribbed intake hose with a smooth one and replace the panel filter with a better flowing filter, my preference is a company called 'green' and you keep the same set up as your car manufacturer spend ££££'s researching and developing, increase the sound a bit, help the flow of air a little bit and its really cheap to do. I also noticed in my time that on smaller not very powerful engines, you lose low down torque by using an open/induction filter compared to a standard airbox, so you make your already slow accelerating car even slower off the mark.

I've been a Journeyman tech for 10 years now and as most people have pointed out there are many many things that contribute to power loss when putting on "Cold air intakes". But the one thing that always seems to bother me, and i know it shouldn't, is no one likes to talk about how 90% of Factory intakes ARE COLD AIR INTAKES. Almost every car draws its air from either the grill or the fender from factory. I mean think about it for one moment people, you dont need a cold air intake because you already have one! If it was as easy as simply changing a pipe and a filter to gain HP the Manufactureres would do it instantly! Anyways thats my rant for the day. As always, keep it up guys your videos always make me happy and put a smile on my face. Good job

exactly, that yellow car was sucking in hot air right off the hot metal intake manifold.
The OEM intakes are usually pretty sophisticated tuned-length affairs, as well as heat shielded. If you try swapping the filter with a panel filter, you will might see a small change if there is a significant enough restriction in the filter (there probably isn't). The only real reason to do a pod filter is if you're modifying enough of your engine bay that it is the only practical option.
@SirDaffyD
11 ай бұрын
So true. I swapped out the stock panel filter with a K&N panel filter in my BA Falcon back in the day, and got a notable gain in power. I then removed the intake snorkel part leading to the airbox, which gave a bigger opening into the airbox to get more air, and got more gains. The snorkel is a restrictive part. I've removed this snorkel to the airbox on numerous cars, and always made gains. There's something to be said about the research gone into the inlet from the airbox to the motor, and removing it can have a negative effect. Every time I've removed the snorkel only, not only have I gained some power, I've also gained intake noise. I do believe they make these snorkels like this to reduce noise emissions, with the downside of robbing some power. My 3 cents.

it only makes less power if the car is otherwise stock. if you tune the ecu by sending it to a company itll fix the top end of the rpm band from running lean and losing power. the ecu can only tolerate 5-10% extra air than it expects before running out of injector pressure to keep up with the high intake volume.

Deffinetely has an effect. I forget the weight difference from stock but heavier tires will reduce appearent power as well since tyno runs are a dynamic test.
It's such a complex issue, but over the years (and thanks to your videos as well!), I think it just comes down to these small cc NA engines being engineered to be incredibly efficient by the manufacturer. Decreased restriction/pressure/velocity in the intake and exhaust probably only benefits FI setups. And in modern vehicles most likely only with tuning in any case.
filter right on most maf's makes them swirl instead of straight sections metering right, also stock box was getting air from a different place not back of engine bay, just some stuff to try
This is actually really good video. It just shows that not everything goes your way. Very keen to see detailed explanation to why soo much power was lost.

So while there may be an overwhelming majority of stock ECU mappings for various cars that can take advantage of the K&N intake, there are other vehicles whose ECU mappings can not. Moral of the story here is the manufacturers claims are not always correct. Remember, they are a business looking to make money. They make a decent product. In the case of the Suzuki, it's ECU was mapped for airflow from the factory airbox. Not an aftermarket intake. Remapping the ECU will allow the car to take advantage of the K&N.

That K&N kit was made specifically for the Swift Sport, so if the MAF wasn't positioned correctly, that's on K&N for not testing it.
When it comes to small changes like a air filter change they need to be tested on a engine Dynomometer in a controlled environment. Chassis dynos just aren't precise enough due to temp, humidity, dew point and barometric pressure, tire pressure, transmission temperature ect ect which effects every parameter of a Dyno run.
Your videos helping me get through a tough time at the moment so thank you for that❤️
The k&n intake for my car came with a heat shield to block excess engine heat. I get around 4-5 more whp after install however if the car is idling for an extended period the air temperature becomes so high that all the gained power from the intake is lost until it cools back down. The placement of the intake is extremely important as placing it closer to hot engine components like exhaust headers can make you lose power even with proper airflow.
The K&N is right at the back pulling straight hot air, The stock intake pulls cold air that's the difference

Had this same kind of thing happen to a buddy's lancer years ago, put the filter right on the mass air. It made great intake noises but tanked his low end and full economy. Then added a foot or two (still made intake noises) and the car was preforming much better.
Had same results. I'm running my polo on the Nordschleife. Went back to stock Filter and shorter intake length. Got best results with stock. Even with tuning on Dyno
The issue for Moog is probably in part the location of the induction kit, you would do better to replace the stock filter with a K&N panel filter in the stock airbox. Also as you mentioned tuning, that is what is needed to take full advantage of a full exhaust system and an intake change, a stock ECU will try it's best to make adjustments to run the engine in pre determined values.

I agree with replacing just the stock panel filter with a K&N panel filter. I've just this mod to a few intakes, and always made gains. So much R&D goes into designing the intake, that totally replacing it will almost always have a negative effect, unless the ecu is retuned to that intake. Saying that, I've removed the snorkel on the intake side of many airboxes, and made gains due to where the snorkel enters the airbox being bigger than the hole where the air enters the snorkel. I've always gained more intake noise doing this also.

When Moog took the stock intake off, he removed the snorkel that pulls air from the front of the car, and by putting the air filter where he did, he is now pulling air from the engine bay. Simply put, he went from cooler air, to pulling hot air which is thinner...so basically now you are pulling less air than you were with the stock setup. Pod filters are designed to allow for more air flow through them, but if the air is is thinner where the filter is, it will cause a decrease in power. Ways to eliminate the loss in power would be to either have a box that closes the filter off from the engine air (with some opening to allow fresh air in) or to run a longer air tube with the filter on the end of it, placing the filter near the front/bottom of the car where the air will be colder and therefor denser.
Would be interested to see the test done again on the same dyno you first done to see if it’s the difference in the dyno itself
Kind of a shame Marty didn't try out the intake hack from the last intake video.

This! Keep airbox, remove resonator and all that spaghetti piping, remove fog light and duct the intake to the fog light hole. Cheap and works
maybe try the k&n drop in filter? could be better results?
I fitted a Growler intake with pod filter on my last car and they stated the benefits would not be noticed straight away as the ECU needed to learn as it was seeing the new airflow settings coming through. I noticed the induction noise straight away obviously but after about a week of regular stop start driving, I noticed the car was more responsive when accelerating.
Rolling resistance makes a difference. This should have been factored in by changing back to the tires used on the first dyno test. After that air temperature could also factor. With the minor incremental claims of increased power these mods advertise, these two fundamental conditions make a difference, from all I have read. Tuning as well could be a factor even though a CEL doesn’t appear. Fun video regardless.

How the car is strapped on to the Dyno also makes a difference. For this kind of testing they should have been using a hub Dyno
The air filter was right next to the hot exhaust. The original air box protected the filter from drawing in the hot air. If you used part of the old air box to protect it from the warm air I'm sure you will see the the numbers back to stock or a tiny bit higher.

Dont quote me. But I think the exhuast side is close to the bumper. So the intake is above the intake side. Still a barmy place for an pod filter.
I think you should have measured them with the stock exhaust and intake in the same conditions (i.e. same day, same (probably higher roll resistance + weight) wheel/tire combo). Also I believe modern cars usually take some time to 'cope' with the changed hardware. I believe these mods overall should have resulted in no power change at all under the right conditions.

Good quality pod filters are fantastic when used in the correct application. Turbo setups with a constant stream of fresh air and closed intake systems that utilise a pod filter will yield good results.
K&N drop in filter is the go to for me…tiny bit more sound and lots more air😍
Moogs "cashed up" character arch is nearing its final form! The stock air box w/ a drop-in high flow filter + ECU tune to utilitise the mods 👌
you got to use the same dyno for comparison, or do back to back runs on the same dyno making the mods. Otherwise its not the same comparison. The amount of settings of the dyno that could change the calculated output just make it too hard to compare reasonably especially if the gains/losses are so small.

Looked back at the previous video and it is the same dyne.
I’m just a shade tree mechanic but I’ve always heard that pod filters like fart mufflers may look sporty but do little if any performance boost. It just sounds like you’re going faster. Fun series.🖖
Unless you go with a pretty large pod filter the filter area is usually smaller in a pod filter than the stock air box. It is usually better to use a performance oriented filter in the air box instead until you go to a mors optimized plenum design or separate throttle bodies. And to really make use of a better flowing intake you usually need to up the cam/cams and an updated tune and much more aggressive ignition. A custom map session on the dyno would probably be my first choice, then cam, exhaust & catalytic converter with a tune.
6:03 you use a panel filter instead. this preserves the "tuned" intake path and increases air flow from the filter as well.
I think the dyno is the variable and maybe even the day itself. If you want to do a test with the only variable being the filters; I think it would show more realistic resuts if you dyno with stock filters, and then dyno with aftermarket ones, all in the same day on the same dyno.
Very much appreciate the honesty and transparency with the intake performance considering that K&N could likely be a sponsor of the show.
I usually add K&N drop-in filters to my cars. You get a bit of intake noise and still keep your air pipe efficiency. Kind-of a win/win. Just don't over oil it and they work just fine, in my experience.
Loving this series boys! Can't understand how you both lost similar power. This is super informative!

Swift lost like %8 more than the 206. The pug was marginally worse. Swftt noticeable loss. Just shows, spending thousands thousands is not always the answer!
A dyno works by measuring the power output at the rollers, by changing wheel sizes you changed the gear ratio to the rollers skewing the results. Swapping back to the stock wheel/tyre setup should give you more comparable power numbers to the first dyno results.

Not if you do it according to the specs. The outside diameter stays the same when you change wheels. If you go from 16 to 17" wheels for instance, the sidewall becomes lower. When a rim manufacturer produces a rim they'll write in the datasheet which rubber to use for your specific car.
Your pod filter was mounted above the engine so it pulled in warmer / less dense air. Your stock filter box has longer, thinner pipes - that helps increase the air velocity going in. Your stock box also has a cold air duct going to the front of the car.
Factory intake system with k&n inlet is the better option, but to remap after the changes is the key 😉
Fun series :) As others have already mentioned, I believe its the heavier wheel/tire combo that caused at least some of the loss. Maybe next time bring 2 of the old wheels/tires and try installing those (on the front of course) to see if it would have made a difference.

I dynoed one on my car and it lost power, and worse filtration
Pod filters work if correctly placed & benefit more from direct cool intake piping and if you can heat shielding / sealing from the rest of the engine bay so cold air only
The original box was enclosed and had a shape that would make air flow in a way the engine likes better. Also, the enclosure protects from the heat of the engine/exhaust. High temperature air makes the combustion worse resulting in lower hp. If you put that pod filter and somehow isolate the rest of the intake, it's probably still not gonna flow as good as the original intake but probably won't lose that much power.
Insomnia FTW!!

Agreed 100%, I don't trust these Dyno results
It's because in both cases, the MAF sensor scaling needs to be retuned for the new tube and the rest of the map adjusted for the change in air volume. If the exhaust are full systems (not just catbacks) same applies to the exhausts. Another factor is that the factory intake is pulling cold air from the front of the car but the new ones pull warm air from the engine bay.
I like how the pod air filter was directly on top of the exhaust mana fault. Got to keep that air nice and warm.
Cold air is the key! Pod filters are great as long as they are put in a place that they can suck cold air.

I would think it would introduce too many variables but not a bad idea.
A lot of cars made now have very well engineered intake systems. For my car it got the most hp gain by just swapping out the factory filter with an aftermarket one. No change in any tubing just stock box.
For my Swift Sport the best air intake was Simota with "carbon" cover. It increased the stock power by 5hp. No oil on it so it doesn't foul the maf reading as well and grabs the air from directly in front of the cars bonnet (you can cut the bonnets gasket for better airflow in that part).
@lukaz861

@Absolute Mad Chad autocorrection hahah. It was meant to say Simota of course. And it's not a lie, I did 4 Dyno tests. Stock was 126bhp, air filter 131bhp, with full custom exhaust 136bhp and remap brought it to 142bhp.
Did the ECUs get a full reset and enough miles to approve whatever emission controls which may be in place? California resident so ECUS and emissions is on the mind..
Really loving this build series
On my swift, I angled the knN filter over the gearbox. I still binned it for a panel filter in the stock box, but that was because i didn't like the noise .
Really like this episode as I have been down this path with my old Ignis Sport. Lost power with a K&N pod filter. Put back the stock box with a drop in K&N filter and gained back the power. Dont understand the engineering behind this, but I just named it Suzuki sorcery and moved on.
You gotta get it tuned to match the new exhuast and intake. Mods add power but sometimes need a tune to bring them to their full potential. It throws the air fuel mix off

Position of the MAF is key. OE airbox ensures best reading of airflow across the sensor. Look at the bellmouths used on ITB setups, a good aftermarket intake has similar design incorporated to keep the MAF reading accurately.
When you increase the mass of your wheels you will loss kw and nm. The hot air intake will also contribute to the power loss. Had this happen to my n/a track car on the dyno. Throw the stock wheels back on and dyno the vehicles again, you will see the difference.

i know a pod filter close to the MAF the "bad air" sometimes mess with the sensor. so a tube and a grid might work. here we some times replace the injector's and adjust it with a bigger MAF sensor housing. that is if the car can use some extra fuel etc. and then the throttleboddy is upgraded if that is a restriction.
For the Peugeot the expanded exhaust piping will have the impact of lowering exhaust velocity, this directly impacts the scavenging effect, which directly impacts the air fuel ratio (aka. power). Going from a 2.0 inch pipe to a 2.25 inch pipe would have minimal negative effects in the lower RPM range while giving a bit more breathing room for higher RPMs. Going from 2.0 inch to 3.0 inch (without large displacement, a turbo or supercharger) will result in a loss of power. Dale covered the basics of this on MCM2 2 weeks ago. As per the Peugeot intake, I would wrap every joint/connection with tape, just to make sure there are no leaks, as any air leaks past the air metering device will have a negative impact on the air fuel ratio. The ECU is expecting a certain amount of metered air, but the reading via the oxygen sensor is different (ie. there is more air present than expected), which the ECU will react by changing the amount of fuel being delivered - thereby taking the engine outside of it's tune operating zone. More air and more fuel is only good if it can be leveraged (ie. it is tuned for that volume), otherwise it is wasted. Along with that, the Peugeot (being much older and likely not maintained) should get new spark plugs at a minimum. If the existing ones are high on the time usage, they will also be out of their efficiency range. Per the Swift intake... The filter element placement is really poor. If possible, I would rotate it to be away being directly over the engine, then try to get/make some ducting that would channel air from the front of the vehicle directly to the air filter. That would help to mitigate the negative impacts that intake clearly has.
It would be interesting to test a K&N filter inside the standard airbox.

K&N filters are shit. They have fewer pleats, which means less airflow, their material is thinner, and instead they soak them in oil to try to compensate for the shitty filter. Want a good filter? Pick something with a lot of pleats, and thick material. The pleats will let it flow better, the thicker material will filter more.
