drop in filter
#5
this has been beat to death.
x 1million
I ask because I have purchased a stock airbox for my car. It came with a k/n fipk, which was way over oiled to begin with. I bought it with the intent of slapping it back in, or just having it in case I want to go stock again. Off K/N's website, it says the FIPK was good for 14 hp but it doesnt list a number for a drop in filter with the stock set up. Thats why I am asking.

paper filter is like 1-2 hp loss over the K&N...not really worth it, that is if you gain any
