Totally agree, got a 20 STI. How many miles till you change your spark plugs?

This is like the ultimate guide I wish I had like 6 months ago lol. Thanks for mentioning the tools, it was one of the biggest headaches when I tried to change mine on my ‘14 legacy 👍

This video should be included with the purchase of any Subaru ….. thank you Mr. Subaru

Really good video, very helpful as always. Thanks for taking the time and effort to educate. I have a 2006 WRX and it takes less than an hour to change the plugs. First time I did it I couldn't believe how fast and easy it actually was. Minimal tools needed to remove the battery, air box, and secondary air injection pump.

I've been going through my new to us 2010 Forester with the EJ25 sohc. Your videos have been a massive help. Bought the timing belt kit from your Amazon link as well as the pulley holder. Good kit, and that job went easier than I thought it was going to. Engine sounds and feels smoother as well as our fuel economy went up a bit. I'm thinking of getting another one of these with a blown motor. It's cheap to get a nice one that way, and I can get a newer sohc motor for under $2k. Cool little car so far, and you're making it an even more enjoyable thing to own with all this info. Thanks.

Thank you for making these videos! They are extremely helpful since I own a 14 Forest and 02 Impreza WRX. I just purchased my first Koken Tools based on your recommendations. I look forward to using these in the future on not only my Subaru's, but a few of my friends Subaru's as well.

Wow. Good work. This was informative and straight the point and very clear. Clearly Mr. Subaru is also Mr. Organized and well planned out. Thank you.

Just did this on my 2020 Crosstrek PHEV, 80k service. It was the most difficult thing I’ve personally done on a car, additional cooling pipes for the inverter made access difficult on the right hand side but when it came down to it removing the rearmost ignition coils were difficult, I didn’t know how much they can bend when needed. Your video and the Koken spark plug socket you recommended went a long way in giving me the confidence to do this. Knocked out the front and read diffs this weekend also. This vehicle hasn’t been to a shop besides tires and it’s been fun to maintain.

Thanks again, brother. I remember doing plugs every 3000 to 4000 miles in my vast number of air cooled VW's in the past and this shouldn't be any issue with my EJ25s on my two Outbacks. Well done, well explained.

I had success changing my spark plugs and am glad to have viewed your video first for a number of tips. My plan includes the following for my 2017 Subaru Outback Limited 2.5L Boxer engine. I did not duplicate the tips as mentioned in the video. Watch the video! 1. Remove items to gain access. (air box, battery, battery holder frame, left front wheel to access battery holder frame bottom bolt). 2. Remove coil packs. 3. Tools used on plugs - 9/16" deep socket, 3" short wobble extension, 3/8 drive ratchet, 5/16" ID fuel line cut to 3" and 4-1/2" lengths, 3/8 drive inch lb torque wrench. 4. The fuel line pieces fit tightly over the porcelain of the plug and allow finger grip to turn the plug out and in as needed. Just feel for proper thread engagement and use finger tightening as much as possible, then resort to tool work. 5. Apply a thin and conservative amount of anti-seize on new plug threads staying away from the first two or three threads (near firing end). My personal preference anyway. 6. Apply a small amount of dielectric grease with a Q-tip cotton swab on the boot ID to slip over the porcelain easier. Notice that the boot plug tip contact is a spring, not a clip. 7. Following Autolite XP5683 with seal washer instructions, tighten 1/4 - 1/2 turn past seat contact (13 foot lbs or 156 inch lbs.) 8. Apply conservative amounts of anti-seize to all other threaded fasteners during assembly. I waited to change the original plugs after 100,000 miles. I had begun to experience some hesitancy at acceleration from a stop. Now the gas mileage has increased 2 mpg on average. Great video! Thank you MrSubaru!

Thank you for this excellent video. It has given me the information as well as the confidence to do this on my own Subaru!

The info is super helpful and I will add these to the list of things i need to get for my car, I am new to the subaru squad! thanks!

Just ordered the 3726k and a 14mm spark plug socket from Koken USA. 20% off Father's Day sale! Got them both for around $128, free shipping and no tax!!!

I honestly only had problem removing the rear driver side spark plug on my '12 Forester. What I ended up doing was putting a flex socket extension onto the spark plug socket. Then a 8 inch extension onto the ratchet. That finally gave me angle to actually be able to turn the spark plug and get it out.

Thank you for this video and the tool suggestions. I replaced the spark plugs, rocker cover gaskets, and plug seals without a trip to the tool store. The Koken spark plug socket worked great! I had (2) 1” and (1) 1.5” extensions along with a Tekton 3/8 12” Ultra Compact Flex Head ratchet that performed well in the tight spaces. A job that a shop would have cost over $1000 cost me about $200 in parts and tools and about 6 hours of my time. For a first timer, it went very well.

Just did this job on my EJ255 Tuesday, but went from underneath for less removals, used a 19mm deep socket on my spark plug socket mostly, not my worst spark plug job, Hemi Durango was more agonizing buried under the windshield and brake booster

Changed my spark plugs on my 2016 Crosstrek. Agreed, the tools make a difference. I found a "thin head" ratchet with a varied selection of 3/8 extensions help. I had to put smaller extensions together to get the length I wanted. After the job, I ordered some "unique" lengths like 5" to keep from having to "build" any. I also like using a piece of old hose like vacuum line to put on the spark plug and start treading it which helps prevent cross threading. The worse plug for me was the one closest to the firewall (back) on the left (driver's) side.

My FRS was a little difficult getting to but I got them in and out in 45 minutes. I watched a rundown and it wasn’t that bad once I knew what I was getting into.

Very helpful! Hope you can keep the good work up!👍

This guy is seriously a guru. Thank you for this. Man... how about those back plugs on the 3.6R. Just did that job 🤕. The driver side one was the biggest pain. Struggled to get the coil out of that tight space. Learned my lesson and got me two gear wrench 90 tooth 1/4" body with 3/8" gut ratchets. I'm armed for the next fight. One thing I found odd, is that even though everything on these cars are metric, the 5/8" spark plug socket fits a tiny bit more snug than the 16mm one on the OEM plugs for this engine. Go figure.

Again, another super informative video. Thanks so much for your time and effort.

Watched the videos and did mines few months ago. That's when I found out my tube seals were leaking. Only problem I had was the plug wires wanting to slide off the coil. If this happens to you put a pick inside the boot when you slip them on to let air escape. Been going strong since then Thank you for our patience and the awesome videos!

Great instructional video. Thanks, Mr. Subaru!

Yep, always having the right tools makes all the difference!

I got a 1/4 in drive long handle 3/8adapter and it worked great.

Great video. Very insightful and helpful. Thank you!

Your videos always helpful! Even without Ko-ken low profile ratchet (can't be delivered to Russia for normal price) it's possible to replace spark plugs.

My go to for a ej dohc is a snap on S9710KC with a 2" extension and a FHLFD80AG ratchet. Depending on the chassis you can use the ratchet as a nut driver instead of going back and forth or using your fingers to unscrew the spark plug. Only time I do the plugs on the under side is when the car is highly modified and it's actually easier/less time than disconnecting intercooler pipes, fuel lines, air boxes, catch cans, and braces. Worst spark plugs i've done is on race sbc and bbc engines with large tube headers wrapped around them where you have to give the old reach around with a snap on S9724RHS and a 5/8 ratcheting flex wrench then struggle to get the new plug started because the spark plug hole is angled.

I have changed the plugs on my '09 OBXT twice. Once going above and the next was under. For me it was far easier to go under the car than above. I have a very thin 1/4" ratchet that works very well to get into the tight spaces.

Ugh.. That #4 spark plug.. ha ha I hate doing this job on my '05 Outback XT. A much needed/helpful video on these cars. This is the perfect example of "using the right tool will make the job easier". The type of job where just 3-5mm clearance can make a big difference. Thanks Mr. Subaru for this great video.

Well, that was an eye opener 😁. Glad we have the SOHC.

An excellent exoplanetary video, Mr Subaru ~ not as frightening as I thought!

Some in Instagram commented about how difficult a spark plug change in a Subaru, then I searched for it and landed straight here…damnnnn this thing is extremely difficult😅

He made it look sooooo simple. But with my luck, something will go wrong or it will take me 4-5 hours. Lol.

I remove the motor mount bolt from one side and jack the motor up on an angle. That angle makes it easier to access the spark plugs. When done with one bank, I replace the bolt. Then repeat on the other side.

ex mechanic here. Some of the more difficult ones, 2000 Toyota Sienna with a 3 liter. Have to remove the hood, to remove the cowling, in order to pull the intake manifold off, to get to the rear spark plugs. 1993 Cadillac Sedan Deville with the 4.9 liter V8. Rear plugs can only be accessed from underneath.

Fascinating, yeah I've used the engine lift method but mostly because I was doing the cam cover seals on my 06 LGT. Other times small hands helps and I use a 1/4 d ratchet and wobble extenstion, biggest problem on the LGT is getting the ignition coils out of the way without scratching up the frame rails. Subarus aren't really hard gm fwd v6s were the worst ;)

I’ve got pretty basic tools and have always been able to access the plugs with a series of extensions. I’ve done 2 or3 changes in my 05 OTB EJ257 I believe🤷🏾‍♂️. I have a question for you, mr S. what about gapping; do you find it 100% necessary to set the gaps properly? I’ve always done it, just wondering if I’m wasting my time.

Incredibly informative 👍

THANK YOU so much for your videos. They are well done !!!!!!!!!!

Any tips on removing coil wire connectors to ensure the often heat weakened plastic clips don't break? I used small pick tools to gently lift and slide. Also, what do you suggest if they do break as I've heard can happen.

21:46 *Flashbacks Intensify* They had no problem coming out, they would just shoot straight into the hood whenever they felt like it, taking the coil with it. We kept rethreading the holes each time one blew out until one of the two rear banks blew out. To much of a pain at that point. I never would complain about my EJ253 in my life 😂😂😂

Thank you Mr. Subaru for your great and informative videos. Question, have you ever changed the spark plugs on an Ascent? I was able to change the plugs on the passenger side but could not get to the plugs on the driver side. Is it really possible to change the plugs on the driver side without raising the engine? Thanks.

Great video do you know how hard it will be to replace spark plugs in a 2020 legacy?

Thank you for the insightful vid. I'm noticing that alot of 14MM magnetic spark plug sockets on the market are 12pt while the hex on a 2017 WRX spark plug is 6pt. Unfortunately, the 14mm Koken socket that you mentioned is currently on back-order. Have you ever used a 12pt 14mm spark plug socket to remove/install subaru 6pt hex plugs? Being that the torque spec is 12.9 ft lbs, I'm thinking the 12pt may suffice.

Did the spark plug on my 2011 Subaru wrx and it was actually pretty simple just need a small 3” extension and spark plug socket

This is my fuel-hose, there are many like it but this one is mine. It is really silly, but best success I had with sparkplug-operation was with a a fuel hose. I'm not joking. It's flexible, it gives just enough grip to the sparkplug, yet it minimizes the risk of ruining the threads. Ofcourse, once it's threaded in snugly, you can torque it to spec easily after that.

I just did the plugs on my Crosstrek hybrid. The driver’s side is pretty easy but there is a thick wiring harness from the extra battery on the passenger side that makes it even more fun.

I personally own a 2005 Subaru outback wagon 2.5l, and have never worked on a Subaru before. I thought it would be a nightmare, even though I used to build race engines in the past, and have been working on various vehicles for over 35years, however I found it very simple, and easy to change the spark plugs in this vehicle. In contrast, my 2015 Ram Laremy 5.7Hemi is a complete nightmare!

Hi Mr Subaru... I'm done with using the bendy adaptor to build up the connections for my next spark plug job... I usually use a reall long wrench and do attack everything from the top and build up the sockets etc... I'm about to buy a flex head ratchet and wondering whether a shorter one is better or shall I just go for the longer version. Trying to get one that allows me to use it elsewhere aswell... Thanks in advance...

The most annoying spark plugs for me were on a 63 40 HP Beetle. All four had been put in by a gorilla and were stripped. I had to pull the engine and install thread inserts on all four of them. Pulling the engine on a Beetle is about as much trouble as removing an intake manifold on some modern cars...

Can you please post or send link for the snap on wrench you show in the beginning. Would that be a preferred 3/8 drive wrench for sparks on an 08 tribeca ?

Just did a 2016 Outback. Entirely from underneath. Didn’t need to remove the battery or air box. (Tho I did remove the two lower battery mount bolts from underneath to buy me a precious few millimeters needed for the driver-side rear plug, which is arguably the hardest one). Just had to drop the undertray. It seemed much easier to do it lying on my back than straining my back leaning over the top. 2.5 hours but went off without a hitch.

I’ve never understood people that struggle with these, as you explained it’s obvious that they just aren’t removing the air box and battery/washer bottle. Pretty much any FWD V6 needs the intake manifold removed to do the rear bank and some of the mid 90’s Mazdas are a full day job to get the manifold off

I want to order NGK spark plugs for my 2012 outback from Rock Auto. Which one should I get?

I’ve found that most fwd v6 vehicles the intake needs removed to replace spark plugs, as you said Fords, Toyotas, Hondas, Usually it’s the support brackets in on the back of the manifold are a pain to get off. Pro master vans are one of few that I’ve found you can get away without pulling the intake manifold. Dodge recommends pulling the intake but not necessary, it’s a bit tighter of a squeeze, but with the right combination of extensions it’s possible and still quicker than pulling the manifold. I would still rather replace Subaru spark plugs than most fwd v6 configurations.

Very useful video!
