I now have the K&N drop-in filter, and have noticed some improvements all around. Since this is so, I am wondering whether I should have installed the AEM CAI outright. Do you guys think there is a significant difference between the two, or will the gains over the K&N be negligible?

My car is the 2002 SE, 4cyl 150hp (stock) vtec

Thanks,

PS: I'm getting the car back today with the H&R Sports and TL-S rear swaybar installed, I can't wait.

 

I say go for the whole intake. It should perform a little better, plus it looks cooler. If you just want to stay with the K&N, then pull out your resonator from under the bumper, and that should give you a little more power also.

 

or you could get into an accident and have permanent ram air like me

 

Where is the resonator exactly?

 

drop-in doesnt provide any real performance gains over the stock filter

 

agreed

 

...unless you remove the resonator and pipe in some cool air from the front of the bumper

i'd still rather have a aem cai though

 

you can do the same with a stock air filter and get the same amount of improvement.

 

yeah I wondering that too, since I cant afford a AEM CAI right now .

 

I used to have K&N drop in and removed resonator on my 4 cyl 6th gen and I don't feel any gain at all The only difference that I noticed is that the loud engine noise under WOT.
