K&N cold air induction kit

Hi, Has anyone any experience with K&N induction kits? I have fitted the full Typhoon kit on my '05 WRX and have the cone in the inner wing with a cold air feed. The problem I have is that up to 4000rpm there is a nice 'sucking' induction sound but going over 4000 it changes to a sort of 'fluttering' noise. Is this normal?

Re: K&N cold air induction kit

have you had it remapped for the change to your intake ? if not I wouldnt be trying to hit high boost especially in the hot weather until you have had it at least checked.

Yes, the map has been tweaked to take account of the CAIK. I am sure it didn't make that sound at first, I only seemed to notice it the last couple of days. It doesn't really sound like compressor surge but it could be I suppose. Just wondered if it was anything to be concerned about
