how much difference is noticed with intake, and what is the best one to get (thinking about comptech). I want numbers if possible but would more like to know, do you notice a difference when driving the car

 

I installed my comptech icebox about eight months ago and I believe it adds about ten whp.

I did notice a difference, especially at higher RPMs. Not drastic, like headers, but worth the money.

Icebox

 

Def. worth the $$...

there really is not any difference in the gains from the CAI to the icebox.....the diff is in the sound...if you want to keep stock sound, get the icebox...if you want growl in V-tec, get the AEM or INJEN CAI.....

BTW - I have a AEM CAI, and LOVE IT

 

Had them both....and love teh ICEBOX.

 

Icebox is gd

you get more low end power as well, with a better throtte response

in WOT it growls
