aem v2 intake

[s2000isu]

Ok I want to start off by saying I am usually a very skeptical about performance gains from exhaust cold air intakes and such. So I installed the intake which was harder then I figured. I found that in the 3-4 k range it feels like a hefty difference and a slight difference up higher. This isnt due to my imaginations from the sound because i had the air box removed before. I do understand that the difference I am feeling could be from the temp and humidity too. All in all I like the intake.

installing an intake is not hard at all if ya know wut your doing. :-/

Did you dyno before and after the intake?? After installing my intake (Injen), I felt a slight improvement down low and maybe a little better throttle response. I love the sound!!

Most dyno graphs do not show much of an increase due to a cold air intake. However some cold air intakes give the "ram effect" benefit. Naturally this would not occur when the car is standing still on a dyno. However you will never know unless you do some test with your car with the CAI on and off. Nevertheless if you like it, that all that matters.

One thing I have to mention about the V2 is hydrolock. The position this CAI sits in the car is right under the flow path of water. There is a drainage hole in the engine bay that causes this, and can be sealed by a piece of tape over it. If you wash your car or leave it sitting in the rain you may end up with water dripping onto your CAI and forming a little puddle of standing water inside the bend of the intake tube. Some people have created "umbrellas" for the CAI, which generally consists of a plastic shield that sits above the top side of the CAI (some people have cut up flower pots etc).

I also cut out the 'brake duct' and placed a mesh grill over it to assist in the ram air effect. I really didn;t worry about the hydro lock problem since Stiletto doesn't go out in the rain, but it is a concern for a S used as a DD.

I dont remember saying it was hard to isntall. Just harder then most of the other intakes ive installed or helped install. I had to take off the plastic on the bottom I had to cut plastic and then I had to snake it in cause i didnt remove as much plastic as i should have.

No I did not get it dynoed before and after I honestly dont care. An intake is not gonna be worth my time. I will only put it on a dyno to get it tuned.

The AEM CAI is time consuming due to the cutting and removing of the plastic underneath. Placing the small tubes in the correct places afterwards can be tricky as well without some good instructions. I had to put one in once without instructions and I had to look at mine while we put in his just to get the tubing correct.

I just returned from Lagune Seca and can verify the increase in performance with my K & N. I went from consistent 103 on the front straight to consistent 108 on the front straight all while being on crappy Bridgestone RE750's

I'm sorry, but that is hardly thorough proof, unless you are a very experienced driver.

As an example, before I had my S2000, I was driving a Mazdaspeed Protege. At Gainesville Raceway one day, I had fairly consistent exit speeds from the chicane after the decreasing radius sweeper in the 40mph range. 1 month later, I went back with no differences other than a different BOV. My exit speeds were closer to 45mph then, and had dropped my lap times by around 2 seconds on average.

Did the BOV make me go through the turns faster? Of course not. After reviewing recordings from my in-car camera, I determined that I simply was apexing the decreasing radius later which allowed me to turn much less sharply through the chicane.

My point is that, unless you have a lot of seat time on a course, small changes are mostly negligible as an increase in driving skill or track familiarity. I'm not saying it's impossible, I just doubt that the intake was the one distinguishing change.

Also, were both setups (OEM vs K&N) done on the exact same day, with the same temperature, humidity, track conditions?

Been to Laguna Seca 4 times and consistently hit 103 on the straight with high 1:50's lap times and over a dozen track days total. conditions were the same wednesday as they were in november when i was there, cool and dry. this time, consistent 108 on the front stretch. i was also really close to tapping the limiter approaching turn 6 and that never happened before either. i'm running the same set of tires as november which was my last track day. if in 3 days there i can do a consistent speed and then i add an intake and suddenly i'm much faster, then i am convinced that the car had more performance.

I can see how a cold air intake could improve your speed a little bit. I actually felt a difference in the lower rpm range and that really surprised me. Top end I really dont feel it but that doesnt surprise. We arent talking about a 30 hp increase hahaha

[bobby2002S2K]

i agree, seems like you know what you are talking about have the track time to pretty much prove your point/test.i would buy one myself but opting for the SC.

[s2000isu]

agreed I want to sc too but I want it paid off first. No point in paying for something that I destroyed haha. Hopefully early next year.

I wasn't there, so I can't say it's impossible. It seems improbable to me simply from past experience, but I'm not going to doubt you on it.

Well the Honda & Acura performance hand book by Mike Ancas (if you havent read this book from cover to cover go pic it up im sure you will learn alot)say that the V2 intake on there dyno shows a 6 to 10 hp at the wheel whether you have the older ap1 or ap2.
