wabster... what kind of INtake did u get?
the AEM CAI does have a noise from the intake. it is low but not raspy unless ur civic is totally different from mine. ie compression and/or exhaust which would pull in more or less air. the AEM CAI sounds good, hell, its almost as loud as some of the exhausts that i have seen.
i DO get a whistling noise if i press the throttle at 35% (roughly)
but i ususally dont have accelerator pressed less than 75%
Hence the great 25MPG that i now get with my intake
also there is all of an 8 hp (At best) gain from an intake alone. so no unless u run on a dyno u will NOT notice the difference in performance, (its not like u put on a turbo or supercharger)
so for NOw ENjoY the sound, and for later watch the HP go up as u r adding the mods
