The performance intake uses part of the stock intake which has the. Charcoal filter on it. So you have to cut the charcoal filter out and then put the performance intake and K&N filter together. Is it worth it, in my option I have it and I could of just put the K&N filter in and cut the charcoal filter out and I would of had the same thing. The only difference is the performance intake air duct is alittle bigger, but you will not notice it. So for the $700 you spend I would put towards a 3 stage manifold or tune or headers before I spend the money on a Performance Intake again.
Just my option
