You're very, very wrong about the plugs, though you're completely right about Slick50, Fuel Magnets and SplitFires. Bosch and NGK are clearly superior to the other brands. I wouldn't use AC sparkplugs if you paid me. Your list is just factory fittiments, not the best plugs for the job. I've talked with a lot of independant mechanics and a lot of people who restore muscle cars. Bosch and NGK are recommended far more often than any other brand. The only people I have ever seen recommend using only the OEM plugs are dealership mechanics, and I'll spare you my thoughts on dealership service departments.Originally posted by: Marlin1975
Yea and when you buy those don't forget to get some Slick50, Fuel Magnets,Split Fires .....![]()
Buy plugs that came with the car. You will have very little to NO diff. with plugs.
GM = AC Delco
Ford = Motorcraft or Autolite
Europen car = Bosch
etc...
