sgarlic said:A FIPK would probably be one of my last choices, especially since for a while there, I read a thread a week minimum about people going way lean to the point of having MIL's illuminated.
jstreet0204 said:There is no way the fipk would make it go any leaner than any of the other two you listed. A bad install might, but the same goes for the others.
BurningRubber said:Hmmm... thats what Im wondering. I have a FIPK and my CEL recently triggered for indicating a lean condition... wtf. I dont see why the K&N would be any different than the other CAI's.
jstreet0204 said:Was the install recent? If so check your connections, especially where the sleeve connects to the throttle body. Mine had a tendency to curl up underneath where it wasn't noticable. Make sure you didn't over oil the filter. There is nothing complicated about the fipk. It's just a plastic tube. If it were a design flaw everyone that had it would get a lean condition.
