we need to know what the best plug whould be for booster02s mustang whould be
fully forged 5.0 stroker mod motor,stage 2 heads and blower cam with around 8psi of boost!
I run Motorcraft part # SP-471, gap at .032 on My Cobra and love them, there the same plug Ford uses on the 2006 Ford GT, just some good info. for the brain lol
I bought a pair of Autolite 764 copper cores because that is the only copper core plugs that pepboys had and I will probably order a different pair but I am going to see how these work for now.
I think I already told you I just put them in there to make sure they gave me the right ones ( make sure they fit). And I dont think I am even going to keep them long .
