Default Help With Spark Plugs....PLEASE
Hi....I have a Superformance Cobra with an older 351W 385HP crate motor. Please let me know what spark plugs and numbers you have had success with. I hear the NGK's are good, but don't what number and if I should get cooper, Iridium, platinum, etc. Also what the gap should be.

The car currently has Autolite 3924 in them and I don't know is the correct plug.

Thanks
