Jim,
I installed an K&N OEM replacement filter on Tuesday of this week
(about $40.00). I don't think you will get the performance that you are
looking for. Throttle responce seems to be better, compared to the
stock filter. Other than that I can't tell you to much. I hope that my
mileage will increase a little? Good luck.................
