Alright, so I'm still trying to research it all out before I do the work and have to do it all again because I bought shit. So far it seems that everybody agrees on NGK TR55's gapped at .05" for plugs and GM AC Delco replacement O2 sensors since the Bosch ones are shit. What about plug wires? This is for my wife's car with a bone stock LT1, so I don't need insane 8mm wires. Would a set of Autolites be worthless? What about the Mallory wires? They're both like $35 a set at Discount vs. $150 for the Delco replacements, Taylors, or MSDs.
