I don't IF anyone else had this or what but ever since i installed my CAI (V2), I keep hearing a screeching noise when I reve the engine around 1800 to 3000. It seems like something is screeching or kinda like wistleing. Tried to rev the engine while in neutral when moving and stoped no noise, But when In drive and the car is travelling at a decent speed and i gas it i hear the screeching noise 50% o fthe time. Any one knows what it is????
