i honestly do not know what gains i got from the CAI...they are fairly minimal, in respect to other mods...the stock air box was very restrictive on my car, so it opened things up a bit. i bought a no new and put on a K&N filter...and on highway trips, ive gotten 29mpg, which is much higher than the advertised numbers...also, my car has run a balmy 16 flat with the few mods (intake, cat back, solid mounts, tires) and the best that C&D got out of a similar car was something like a 16.70...so something helped...
