seriously tho.. I love my sport 500's. If you are gonna put up the cash for some stockers you can find a good set for 1000-1200 bucks, or pony up a bit and get a good upgrade while your in there... so you don't have to pull the motor again.. then get new injectors before your stockers go out.. no sense in not upgrading while hitting some preventative maintenence (splng..) anyway..
