Car Guys... Cold Air Intake (Induction) is it worth it?? Any car people out there? Been pondering on the idea of installing a K&N cold air kit on my car. I'd get a 7-8HP gain, but it would set me back about $230.00. I did already replace my stock filter with a drop-in K&N and I love it. Have not removed the air silencer as of yet, but I'm considering it. I've heard that removing the air silencer and adding the K&N filter is equal to paying the $230.00 for the induction... as far as performance gains/flow is concerned.... Anyone have an opinion?
