Ok, i managed to pickup my adapter for my fuel rail today, drove 45 mins (45 mins 1 way, then back ) for a 5$ adapter....almost funny~ ANYways i went to autozone and asked for a 1 or 2 range colder plug for my stang, first they tried to sell my platnum plugs and i kinda laughed , next they dont anything listed about heat ranges, I need the part number for 1 or 2 range colder plugs for 2.3, that would just about as good as it gets! anyone who could help fill me in on this, would be my best friend
