fuel economy with the AEM CAI? I dunno if it's my imagination but I noticed a 20 mile increase at my last fillup. I average 220-240 miles before I the gas light turns on and I have to fill the car back up. But after I installed the intake, I got up to 266 miles before the gas light turned on, that's approx gain of 4mpg. Even then, I only filled up 11 of the 13 gallons..

And my driving habits didn't change, this was mostly city driving with plenty of VTEC, WOT all the way..

 

that would be interesting

 

that is crazy, i dont VTEC that much in my car and i get like 185-195 and the gas light turns on.

 

In my prelude I got better gas milage when I installed a CAI, I guess its the efficiency

 

i also noticed an increase in fuel in economy when installed my AEM cai on my integra, it will be nice if smae holds true for the S2000.

 

If this thing will gain gas mileagefor the S...even it won't make any HP, I think I will buy it regardless...!!
