Alright, I need some help. I have been hearing that the TR6IX is the spark plug of choice, I know, but here is the problem. I have a hook up at Pep Boys and they cannot get those plugs. The offered me the NGK iridium platinum (part # 1465) This spark plug is normally $11 and I can get them for $5. That is just an example. Can you guys offer me some other options for great spark plugs or is the TR6IX the end all be all for plugs with this car. Help!
