I installed my K&N CAI about a week ago. Installation was straight forward. I did notice something new. Something that was not there before. When driving around when the RPM hits about 2.5k I hear sound coming from the engine. Air the be specific. Not quite sure how to describe it. Like a vacuum I guess? Should I be able to hear engine sucking in air?
