Default AEM Cold Air Intake - 2011 WRX

Got an AEM CAI installed on my car 2 weeks ago. Just wanted to write a quick review for you guys.

Fitment is really good and it looks great in the engine bay. The filter is placed behind the bumper and it has a heatshield so the intake is definitely getting some isolated colder air.

The sound is pretty sweet. Much better than how my spt intake sounded on my 07 WRX. I can feel a a noticeable difference in response after 3k rpm when the turbo begins boosting.





I also did a quick airboy road dyno on the car to see the power with the new cai on. Unfortunately I did not get a road dyno for the car without the intake on so I cannot say exactly how much power I gained, but when I get a chance I will post it up for you guys.

Again this is power to the wheels, so if this road dyno is somewhat accurate the power should be somewhere around 293 crank horsepower.

I noticed this intake tends to go lower than most other intakes do. how high is the long ass AEM filter off of the ground do you see any paths to potentially ingest water if you were to rip through a deep puddle? thanks.

Interested in the answer for this as well.

Intake looks sharp! ok, now put the stock intake back in and do a road dyno in similar weather conditions on the same road

Did you get a tune after you installed that CAI? (I'm considering this CAI, but want to know if I need to get a tune or not, or just reset the MAF sensor). I read that this CAI is different than others. Something about its internal design that allows the MAF sensor to auto adjust, I don't know. Oh, is everything else stock? thanks.

I did not get a tune after installing the CAI. AEM and others on the forum have mentioned that a re-tune is not required to safely run this CAI.

I have not done research on other CAI, but I do know that AEM puts a good deal of testing into their intakes. The internal diameter of the intake is designed to optimize the stock map's air fuel ratios throughout various parts of the power band, because we all know that the stock map has some funky AFRs. It's not as completely optimized as a re-tune would but it does enough to increase power a little bit.

My friend showed me some data that compared the AFR of AEM CAI vs stock I think and it showed how the AFR is shifted to a more efficient zone in various parts of the power band. I might be able to get some of that data from him.

And yes everything else on the car is stock.

And to answer the question about water ingestion. The intake is located above the plastic undertray piece so that would help block the filter from ingesting water. As long as you are not accelerating while being submerged in a pool of water I am sure you would be fine.

thanks! I might consider it now. Anything tricky or difficult about the installation?

I actually did not install it myself, but it seems pretty straight forward. It comes with installation instructions too.

right as I was about to pull the trigger on this I saw that cobb has their SF intake for the 08-11 models available. it sits higher in the engine bay and has a nice airbox option. tuned gains are similar to the AEM model.

if you are concerned about running through deep puddles like I am, probably a better route, but I bet the AEM produces a better note due to the filter size and location : )

I saw this as well and may go the COBB route. Looks clean too. Just wait for a black option.

just so you know, AEM makes a pre-filter wrap that protects the filter from water splashes and dust. They have one that specifically fits the 9" filter this CAI uses

Yeah AEM sounds very nice. Cobb short ram intake is good because it has that nice heatshield, but I don't think the air will be as cold as AEM.

So it's been a few months...have you noticed any I'll effects from the aem unit? And how many miles did you have on that beautiful machine before you put the cai on?

All of these things I must know, I have the same car and I'm really needing that throaty sound of an intake to couple with the turbo spool.

Thanks for the compliment, yours is probably quite beautiful as well. SWP baby!!!

I think I had about 1000 something miles when the cai was put on.

No I haven't noticed any bad side effects from the cai. It just really needs to be tuned to really see any performance gains. I will probably be flashing my car to an XPT stage 1 map or putting on my catless downpipe and getting a custom tune soon.

It's all about Money. A company needs to pay to have an item tested and certified in order for that company to legally say that their item is CARB legal. Yes, it's the same intake, and yes, it's only 2008 CARB certified.

Bummer.

Hell yeah, no need to retune! Subarus are known for their ability to easily adapt to changes in the MAF.

I have a Magnaflow 3" cutback on my 11 WRX. Any idea if adding this intake will require a retune? I'm skeptical about installing this until I know for sure.

Thanks. Looking for area tuners in VA/NC now, probably going to go ahead and get a down pipe installed as well.

Will I fitted a AEM CAI to my 2011 WRX and I absolutely love it!!

There was a very noticeable increase in power and acceleration as soon as I installed it!! With stock tune

Peace of cake to install and full factory fit straight out of the box..highly recommend it!!

I have since upgraded to a catless down pipe and stage 2 tune by Torqued Performance and holy **** my car is a weapon!!! So fast i had to upgrade to Sti Brembos and slotted rotors as the pathetic oem brakes would get glowing red under heavy braking due to the massive increase of power!!!

My mate has a factory 2010 Sti hatch and mine absolutely smokes his off the mark and all the way through, so very very happy
