Just buy a K&N air filter and replace the one in the box now, or if you want it for the looks K&N and many others are around all depends on the price you want to pay.
Check out R2C Performance. No oiling required and dynod an extra 15hp/tq at Mr Norms. Im happy with mine had my tune redialed in with the added Air. My tuner added extra fuel to beef up the air/fuel mixture. If you dont tune it in there will be no difference. Also changed the Throttle body to 85mm. Gained 12% overall in the powerband.
