hi guys im debating wether or not get a cai for my 2001 mustang i heard they don't do much. but i need a real honest opinion i have dual exhaust on my car now and i'm planing on doing the j mod the intake spacer from vap auto and a custome tune from vmp tuning. now is a cai necessary for best results or not? i currently have a k&n drop filter in there. is that enough or a cai will give me more hp?
thanks guys

 

CAI = 2-4 rwhp, you make the decision for yourself....

 

kool how about the k&n drop in filter?

 

should be about the same. it wouldn't be a noticeable difference, i had a drop on k&n...when i put on a cai i didn't notice anything different but sound

 

its worth it if you like to hear your car sucking in air. its pretty cool though, no lie.

 

thats very true. plus is looks cool.
