Has any one tried the K&N Ram Air Intake, it looks great and K&N has been proven to perform.

 

Its expensive but i would say the T1R cause it looks better to me and it looks kinda stock to plus its and air box like factory almost, so it the best of both intake worlds. Intake tubes make extra noice and if some one wanted could say its a reason to void warranty when you take it in for service. but did I say expesive. No I use the passwordjdm power chamber its not to loud to me it makes the car peppy at low rpm and it looks great with carbon cover. Plus come with new battery which I was told stock batter causes acid which causes corrosion which helps rusting So I spent about $570 all togeter for cover, air chamber, battery, and wires. That might be alot but its the only mod I did on my fit besides s-tech springs since I bought car last june, and all of it is still in the box. And no this is not actual pic of my engine bay mine is way dirty to show.

 

CAI will get you the best MPG probably.
but the T1R chamber intake will be most useful on an AT. the powerband is larger.
