Honestly i had a "Ebay" intake for 5 months and i didn't experienced any changes on my prelude performance, by the way the filter was a piece of crap and i got from "procarparts", then i decided to get a AEM and now i really feel the changes especially when i'm in 1st or 2nd gear. feels like auto tranny somethimes and i need to keep braking the car to drive in parking lots and stuff and is hillarious because sometimes my car gets a little nervous i mean more powerful, i just loved the real intake one, i still keep the other one, i guess was the horrible filter or who knows i couldn't believe and i paid almos $50 for the ebay one.
