i have a HAI on my car right now but recently my friend with a GSR who has a HAI upgraded to a CAI and i noticed a difference in his car so im wondering if it would be better for my car? im auto and ive heard that at the top end it isnt as good but im not sure. i know warpspeed has a pretty good deal on CAI for our cars so thats why im wondering

 

Theres a bunch of threads out there that debate this exact question. Most people argue that CAI is better for autos and hybrid intake is better for 5 speeds...which is what I tend to believe. In my case I have a PR CAI on my auto and I am very pleased. Dont hesitate to purchase it...you wont regret it.

 

just take your stock airbox off, its better than either one.
