Default AEM Cold Air Intake

This is a great intake, but don't expect great gains in speed right away. Installation was VERY easy, and took me about 90 minutes(never done anything like that before: a pro could have done it in 45 mins). It sounds spectacular(for JUST an intake), especially above 4500+ RPM. I've heard that you can actually LOSE horsepower by installing this, but I think that is a load of crap. I noticed barely, if any difference in the positive. Partly because the stock cold air intake ain't bad, ya know? Farther down the line, this intake will allow for bigger upgrades in such things as nicer turbo, etc, and will make a noticeable difference in speed and response AFTER my car is more powerful. You will lose weight and gain a lot of free space because the stock air intake, resonator, and filter are removed. The stock air sensor fits right in, and no additional problems or complications from the install have been noticed. All in all, there are better things you could spend you money on as far as upgrades, but this is a great intake, from a well-known company. I plan to purchase future AEM products based on their intake's performance.

The whole "CAI's will do nothing for our cars" is a myth by people that don't have one :monkey: The crap about your car will run lean and run bad it all theoretical at best.

Try driving your car for a few months and get acustomed to how your car drives and accelerates with a CAI installed. Then go ahead and follow the crowd thinking your CAI was a mistake and sell it and go back to the stock setup. You'll be VERY dissapointed that you sold your intake. I know I am

Mitch808, I thought you sold your Injen becasue you had some other mods planned (FMIC?).

I love my CAI (the sound is amazing).

I have a AEM CAI and just installed my buddies short ram AEM, the short ram is better. it allows a larger volume of air and it does increase the NVH though.

I just did a write up about the AEM CAI on my website. This intake is a great addition to any WRX. I measured a 1/2 PSI reduction in pressure drop through the intake using a manometer. This reduction in restriction really helped power in the upper half of the RPM range, the drop off in power isn't as profound above 5500 RPMs as it was before. Also, boost response is improved & the sound is great. I give this part a big .

Here is a link to the test & review.

Sincerely,

sorry to bring this thread back from the dead, but i thought i'd post my impressions of this part:

1)nice quality
2)great instructions
3)excellent fitment
4)sound hasn't increased that much, if at all
5)the car pulls a lot easier and smoother past the 5000 rpm mark, whereas before it just kinda died off

all in all, a great part, and hopefully it will help out even more once i upgrade the stock turbo...

Oh I used to have one of these. Compared to a shortram you can't really hear it spool. Though there is some sound. This is a good intake!

I'm very pleased with my AEM CAI as well. I used to have the SPT hot air intake and heat shield (still have the shield installed), but I never could get used to the boy racer spool sound from the SPT. So I sold the SPT and went with the AEM...which is less expensive than the Prodrive version.



No drivability issues whatsoever, engine seems to spool up faster than with the stock airbox. It will however make you run a little lean in the lower rpms...but after downloading the Cobb Stage 1 map all is good.

I used to have both the SPT and the AEM. SPT I can say really sucks because of all the heat it takes in. The AEM CAI ran pretty well. No problems with it! Much better then the heat the SPT gets. ALthough I sold mines because the "Band Wagon" of Intakes are bad! I regret it. So I just bought my Injen Red Rinkle CAI! Can't go wrong with that!

Pleased with the results including the AEM CAI.

Just bought and installed one in my 05 WRX. Super easy installation. It took a day or so driving, but I can definitely tell a difference in accel, especially over 4500 rpm's. Very satisfied, and can't wait to map it.

The AEM CAI was the first thing I put on my 06 TR when I had it. I ran it for 20k miles, no issues at all. I liked the way is sounded and it ran great. So I swapped it over to my 06 sti when I traded in my TR and put another 10k on it since. Still runs great with no idle or any other issues at all. Bolted right in with no problems and fit good and everyone who sees it says it looks good too. I'm running cobb stg 2 now in the STI with the TBE and I'm like'in it.
The cool thing about the cobb STG 2 is the acess port. I dont know exatly how accurate it is, but it has a air intake temp gauge on it. I run around with in on that and I have noticed that my temps are usually only about 3 degres above the outside air temp if I keep it above.... like.. 30 mph.

I read somewhere that it doesn't really matter how cold the air is coming into the turbo since it's only going to heat up once it hits the housing, not sure if that's true but it makes sense. In all reality the higher flow the intake, the better. Not necessarily how cold the air is coming in.

Well I guess as with anything, it takes a longer time and is harder to heat up something that is colder to start out with.

IMO- The AEM CAI is a mistake on the stock 2.0l. I made more peak hp, but far less initial tq than a modified stock box w/ drop in K&N. Moved everything on the dynograph to the right, with little peak gain. This was with a VF29 300whp E85 setup. Went back to the modded stock box, and it helped ALOT with gutless off-boost starts, but pulled about the same up top. Probably not as much of an issue with the 2.5?

Anybody with this CAI installed on the 2.0 want to chime in? I'm thinking of getting one for my wagon. Still have stock TD04, big TMIC, tune and a few other mods. I want to make sure I'll be getting something out of installing this.

I have a SRI but a friend of mine has the AEM cold air , and he got 265 wheel on stage two , it is a JDM wrx however but good gains with the intake.

Thinking of changing mine for an APS cold air , seems pretty hybrid.

I have a K&N typhoon on my 02 wrx. Torque was a definate increase. You can feel it pull as the sound increases it feels amazing. I heard great things about AEM also a friend of mine has one on his nissan 240.
