I'd reccomend K&N. I have had mine for over 2 years and love it. I know people say they haven't had Check engine lights with the Injen
, but I have NEVER heard of anyone having a CEL with a K&N. plus there is no cutting and splicing the computer breather tube and new hoses or anything like that. You re-use all the stock vacuum hoses. It took me 2 hrs. tops to install it and love it.
