Autolite Race Plugs feature the latest plug design technology. Their multi-rib insulator, copper center electrode, large cut back ground electrode (covered in nickel plating and sealed inside a longer insulator to resist carbon fouling), and double terminated suppressor provide the best EMI suppression.

NOTE: Plugs are priced individually but may only be ordered in sets of 4.
