Currently I have a K&N air filter with the silencer removed. My question is do I really need a aftermarket CAI for extra air coming in? Is the stock air intake very restrictive?
Btw is that a good thing not having that snorkel silencer there?
Yes. It's a restriction. I picked up 16rwhp when I took mine off. Did one pull bone stock, then pulled the silencer and it picked up 16 wheel. Good enough for me.
