K&P makes them for everything... I think Scotts buys them from K&P.
K&P Application
I got a guy that is a deal for the K&Ps
And yes they are in the $100 range. But do the math on it... say $12+ per K&N... less than 9 oil changes and you're home free.
Plus I know a few guys that told me that after they went to the K&P, sense you wash it out yourself... you see everything that has been filtered. They found paper in there for a the first few changes.
