has anyone that has the K&N noticed that after a while, the sound of wide open throttle becomes quieter? i'm pretty sure i'm not crazy, but i dont think its as loud as it was when i first installed it.
Could it be that in disconnecting the battery you caused the ECU to re-map itself? Don't know just trowing out a theory. Once I put on the JOE Z exhaust I could not tell if the K&N was still under the hood,,,,,everything is just loader now.i unplugged the battery, then reconnected it. drove for a bit, then let er have it. i think its louder again.....some people should try this and see what they think...
your probably so far from correct you should just delete that post. i've only put on 4000km with the k&n, and your telling me, after that my filter is dirty. on top of that, when i made this thread, it was after around 200km that it started to get quieter.Check your filter. It probably needs to be cleaned.
