odometer hit 75k miles a while ago and the car still has the originial plugs as far as i know. I want the best performing plugs at any cost. what are my options and where should i order them.
'05 sunfire. rksport intake, 2.25" custom dual catback, b&m short throw pacesetter header and high flow cat.
I had bosch Platinums waste of cash, My car ran funny. I put AC Delco back in ran flawless. Ive been running them in for 30,000kms no problems. If the GM Tech recommend it, And the J-body guru's know best.
Good Luck.
