Spark Plugs?
Agreed

Platinum plugs do tend to last longer, not 6x longer though. I have also heard that some lt1s dont like different plugs, have not seen any proof of this though. I still spend the extra $ for acdelco platinums, when you consider the amount of time between plug changes, an extra 20ish bucks is nothin.
i wouldnt run a bosch plug if you gave them to me. ive killed an engine with them the ceremic fell off inside the cylinder
