What after market air intake system are most of you guys using? I did a search on K&N's site by veh,year,model and came back with a replacement air filter and oil filter. What's up with an air intake system....

You aren't saying just leave the stock airbox the way it is, of cource? What do I add to the "stock airbox" to enhance it even more?

put a clean new filter in it.
