How To Install a Air/Oil Separator for Subaru WRX & WRX STI! (GrimmSpeed)
The GrimmSpeed™ Air/Oil Separator for Subaru vehicles has a unique patent pending design that allows you to maintain your PCV Valve while separating the oil out of the crankcase and head ventilation air! Our AOS will allow your engine to run more efficiently due to the separation of oil from the intake system. When there is oil in your system, the result is 1) reduced fuel octane 2) higher chance of engine knock(detonation) 3) worse emissions 4) higher oil consumption. Our Air/Oil Separator will help all of these problems. Thank you to Grimmspeed for providing the parts for the #throtlwrx!

The people suggesting a Front mount IC, probably have never modded a Subaru. Unless you're going with a bigger turbo, don't do FMIC. It will introduce a fair amount of lag. The more ideal setup would be an upgraded (or STI) top mount intercooler.

Mickey I'm a plumber and when I see mechanics cutting hose, I always think; they would love a "pex cutter" for nice clean cuts. I don't know if you have ever tried one but they are cheap and you can pick one up at any plumbing supplier or most likely a decent hardware store. They are incredible sharp and support the hose or pipe for very straight cuts. I'd recommend the Milwaukee tools' cutter if you want to go high end. It's important to twist the tool as you cut but they would beat a pair of scissors all day.
Just now seeing this and plan to install on my blobeye. Appreciating the well made tutorial 4 years later!

I may not have a build in progress but throtl has become one of my favorite automotive KZread channels since you guys started the channel. I love the concept and bringing people together through the automotive aspect is one hell of a great thing.
I wouldn't go for a FMIC, but I would upgrade to the STi top mount one. Better performance (it's a bit larger, so it flows more air), and retains the stock location. FMIC introduces too much turbo lag to justify getting one.

I am really enjoying these wrx vids and Mickeys vids
Glad to see ya Mickey, as been missing you on TJ Hunt channel; so, glad your at least on Throtl with Evan & crew😊. Hang in there & keep head up when feeling down, things get better. Also love learning new things from you about diff after market performance parts(never used GrimmSpeed Brand) , as YOU make it interesting & fun; not boring & dull. THANKS‼️ Cheers, A #mickeyandrade
Going FMIC might get you some hot boi points but that's about it. Yes, it might look better to some BUT going FMIC is going to increase turbo lag with that tiny TD04 turbo and the install of one is definitely an all day or multi-day install (lots of cutting). If you go FMIC, you should at least get an STi VF39 from that generation. If you want a better intercooler, hit up your boys at Grimmspeed. They make a really nice TMIC that's good to ~500hp. It's a much simpler install, pretty much a straight swap. I run it in on my '04 STi with a larger 20g and have no complaints. It would also be the perfect time to change the Y-Pipe to a silicone one because after 14 years I wouldn't be surprised if the factory plastic one had seen better days.
If you want to go front mount, upgrade the turbo. The old stock tdo4 won't be able to fully utilize it. If you stay stock turbo then go with a better top mount like and STi version or a Grimmspeed TMIC. The turbo will work well and they are good for power in the future. I would also say if the plan was to track the cat or go big power right away then front mount and slightly better turbo like a 20g hands down. It would be a happy medium. That's just my 2 cents! Love the vids guys! Keep this up! The positive vibes, the installs and overall informational content you provide is good for every beginner or advanced car nut!👍🏾👍🏾👏🏾👏🏾😎😎
From all the other videos ive seen, the middle port is the clean return to intake
I do like the video's with Mickey, 1 he tends to know or have a pretty good idea of how things work, 2, is very good at putting techno babble in to english, 3, he shows what he is doing clearly and also talks us through each step while he does it so we see how why and any changes to to say the rout of a pipe and why, if it is looks wise he says so if it is because it will screw up he says so and why it will screw up. Mickey Spec Mickey Teach. Mickey the question I have is this unit that you need a wheel brace or a 19mm socket to undo is $200 a catch can is around $26 - $35 can you say hand on heart that it is worth the extra spend.
I love how Mickey is so descriptive in the videos, will definitely purchase this item for my subie
I’ll never not love Mickey’s dad filming and exhales!
Fmic's are cool but Grimspeed makes a nasty top mount!

You are going to need hose clamps on all 3 of those hoses directly off of the AOS itself. Ask me how I know haha. You said they aren't pressurized, but I had a boost leak while getting tuned coming directly off of the AOS itself. We did a smoke/boost leak test and it was leaking from the zip tie. You need hose clamps at least on those 3. Lastly, if you want to change the stock intercooler then just upgrade to an sti one, the oem sti top mounts are good to 450 awhp.

William Bittner they top mounts from an STi are basically useless after 370-380whp.
The WRXs small turbo doesn't push enough boost to warrant a front mount. Stock turbos with FMIC usually lead to huuuuge amounts of lag.
Agree with the comments below. In the UK you can very safely push the 2.0l engine to 350-400 on the top mount. Really only do FMIC become beneficial is for big power gains. My Litchfield JDM ran 360bhp/350ftlbs on the top mount. A friend of mine has over 400+ on a top mount but his is a 2.5l forged engine
Tech you could get a fix it ticket for a FMIC, but cops are WAY more likely to bust you for exhaust, or a huge intake if you pop the hood for them. I’ve never heard of anyone getting a ticket for a FMIC. Anyway, with the heat you guys are having, def go front mount, your B.A.Ts will be way lower the just upgrading a top mount. Loving the channel bruv, keep up the great work!
The way you put the videos Mickey is really great and the music to. Thanks
Well I love the look of the front mount on a Subie and delete the hood scoop...I had one on my WRX in San Diego, CA!
I had buddies swapped to front mount and didn’t have issues getting their inspection passed. I had a bigger top mount and called it a day in my subie.
ayy mickeyy lilttle tip for hose cutting a pvc pipe cutter works really awesome on cuttiing those hoses at mickey spec..
Honestly I love these vids, but I think that IAG makes a better AOS. Still a great part for a subie. (I own an 05 sti)

ThatsJimmii to be quite honest IAG put a lot of time and effort into perfecting this aos and it really shows. There is no longer any oil trapped in my intercooler with all that blow by. So here’s how I see it based on what I have and people I know personally, who are running certain Aos’s. IAG top of the list because again design is flawless, Crawford second because they weren’t even suppose to have these for resale and was only made to take care of a problem on the track. So some thought was put into it, and my friend has one and has nothing but good things I say. Perrin third because it’s affordable and designed works alright lol. But grimmspeed NEVER.

Street Legion Hey, by any chance do you have an Instagram with your car, it sounds like your car has gone through a lot and that’s pretty cool. Mine is literally thatsjimmii on there
Def go with a fmic. Perrin makes nice fmic kits. They have the stealth series in black. Looks absolutely sick. Some of the ppl commenting saying fmic result in lag and what not. Yes to a certain degree it’s true but it’s all down to the tune. Plus with a fmic it leave so much more room to play with if u decide to go big in the future. If not fmic then definitely an upgraded tmic. Even a stock sti ones are not really an upgrade. Something like a processwest or turboxs tmic are one of the thickest ones on the market.
I dont know what my first mod should be. This car is turning out to be amazing, also I think you should leave it to the person who wins the car to decide whether or not they should front mount
I'd rather go with a bigger top mount like a Process West or ETS. Bolt-on and makes the bay look a lot better too. Another great vid guys! Loving the content!
Get the Grimspeed TMIC and the upgraded throttle body to TMIC hose or the Inlet Hose! Look great and support greater power for the future!
For the love of god, do not get this for your subaru and get a proper AoS like IAG or even a catch can

STi top mount for a good budget intercooler or Process West top mount if you want to go full send. A FMIC is just going to get you more turbo lag with no real benefits on a stock turbo.
Same thing as an oil catch can basically but instead of emptying a catch can it just empties into the oil filler. Nice little rig.
You connected the first hose you cut for the AOS wrong, it was supposed to connect to the center of the AOS not the left side

I was going to mention as i just installed one on my own car, glad this was in the comments -- maybe we can get it bumped for anyone watching for an "install" video
If you dont go with a bigger turbo id suggest the fmic but with smaller charger pipes then what you might want so the added length in charge piping doesnt cause more lag
Love this channel... All about cars and it awesome... For me just upgrade TMIC and no need FMIC.. since turbo is stock, FMIC will only create lag not performance...
I can’t wait till I can actually start working on my bug eye that engine bay looks so nice compared to mine
Best thing to do is get a bigger top mount like a grimmspeed, process west, or even just an STI top mount for the car it will run better and not have as much lag as a front mount with the stock turbo.
Love the videos guys keep up the great work !🚗
Throtl heart could save my week♥ :c
so it's basically a catch can that puts the oil back in the pan autonomously?
Front mount prevent issues with heat soak in warmer climates where temps reach high 90s or more
I think you installed the hoses wrong. The one in the middle goes to the hose connected to the intake manifold. The other two on sides go to the hoses that come from the valve covers. Correct me if I'm wrong. Thanks.
Same I’m not really a fan of top mounted intercoolers because it’s hard to upgrade also I think the new Toyota sequoia and tundra have that too now
Get the STI Top mount IC and also the STI hood scoop you wont get more turbo lag but wil get cooler inlet temps
Front mount is a must!
Yes I think a front mout is the best and it also looks better
Nice Mickey. 1 handed beast👌
I think because a front mounted intercooler is a matter of opinion rather than function it’s something that should be left for the winner to decide whether or not they want it because I know if somebody who is really big into the Subaru scene or is a big ej fanatic wins they’re probably just gonna switch it back to the top mount intercooler
Glad he said he was gonna throw some zip ties on the connection for air to oil separator at the end of video I was getting a little worried lol
No front mount, just upgrade the top mount.
Dude had to have been buzzin when he filmed this
I thought it was a Cobb acceport 😂😂😂 love your videos
Front mount intercooler is the way to go !
Go front mount prevent heat soak make that lil wrx happy
They make decent top mount upgrades as well.
Front mount for the win!
I agree it needs a front intercooler
I've had 2 grimmspeed AOS go out on me, I would honestly stay away from those. Id recommend the IAG AOS
Do a Grimmspeed top mount ic. Better than a front mount, and looks efficient.
Front mount intercooler a must
yes that needs a front mounted intercooler. i agree 150%. Mspec

Mickey do the front mount intercooler and whoever wins it give them the stock air cooler so want to comes time to do smog it’s a easy enough switch over 👍😊
If it stays on the West cost go big front mount, if it goes up north where there’s snow keep the top mount. But you guys wouldn’t know who wins it, unless I get lucky, OOOOHHHHH YEAAHHHHHH!!!🤩. If that’s the case stay front mount 👍
Be aware also if you change the intercooler to a bigger core or front mount or run an atmospheric blow off valve it will require tuning.
Mickey is a G man fr
Frontmount intercooler to clean up that engine bay just a little.
Gotta say: Those are some workin' man's hands!
Stay top mount, just go to a bigger core. On Subaru's especially a WRX. Switching to a front mount intercooler without upgrading the turbo will cause significant turbo lag.
yes put a fmic plz. and make a video on it.
Process west make a beautiful top mount but vertical inter cooler
really looking forward to the end product wrx.
Bigger turbo then front mount. As front mount on a tiny tdo4 is overkill I got mine when i had my tdo5 hybrid fitted by oma performance tuning
Yes front mount
Oversized top mount to stay carb compliant. Front mount won’t pass visual unfortunately
I do agree with the top mount inter cooler....it's an eye sore. Could you maybe get a diff top mount one, if not able to do front mount? Maybe that's a better idea, especially if it keeps it within carb compliance etc.....mJust a thought! Cheers, A👍🏻👍🏻😄
Front mount for sure
Please do a front mount
Yeah do a big front mount
Go with the mishimoto front mount
WRX are very touchy about mods. A lot of mods require tunes. A FMIC would need a tune for sure.

Oh and killer b let’s not forget those guys. They make awesome stuff as well. Heard their AOS is top notch, although I haven’t owned one personally. I’m sure it’ll live up to the hype.
The grimmspeed AOS isnt capable of passing CA emissions, so you might as well Full Send It - mode. For a street car, having a front mount on the wrx isnt going to make that much of a difference unless you live somewhere hot or plan on sitting in traffic a lot. If someone wants a front mount for making big power, theyre going to have to do major motor upgrades looong before the need for a larger intercooler. The slightly larger STi top mount intercooler is a good OEM+ upgrade, and still passes CA smog. Will still require a tune of course.
Should definitely do a front mount!
Already put a bunch of STI stuff on .Throw the STI top mount on it and call it a day.
Bigger Top mount if the turbo is staying standard.
no one noticed that he routed the center port on the AOS to the crankcase vent and not the intake?! The center port, or “cleansed hose” goes to the intake
I think a front mount would be a great addition to the WRX!!!!!
Front mount! I have a 04 wrx same color and all have the motor out putting it in this wkend and im really dreading that intercooler its a bitch! Wish I could drop the motor in with it on but I can't
man, I just dont know about the Grimmspeed AOS, I mean look at the Perrin, IAG and CRAWFORD AOS comparred to this GRIMMSPEED. It just seems like its more of a gimmick than pure function!! I don’t know, just the feeling I get!! I mean it’s a hell of a lot easier to install the grimmspeed vs the other 3 but I just feel like it wouldn’t be all that effecient.
For sure a front mount intercooler...might get a little more lag with the factory turbo but temps will be fantastic and you'll free up some engine bay room
I don’t like the idea of draining the catch can vapour back into engine but I know nothing so it’s probably alright
Definitely put a front mount on it
Go with a big tmic and swap the turbo to a vf39 and the wrx will be good to go
