SPARK PLUGS M8/XG

Plugs have a unique look with a black ceramic body and bold red logo/script

Insulator is made of 95% pure alumina, features strong resistance to heat shock and superior insulation

Multi-rib design of the insulator eliminates flashover

Nickel-plated housing prevents oxidation and corrosion

Multi-layer gaskets and heat crimping process ensure a leak-free, gas-tight seal

Copper core electrode prevents oxidation and corrosion, has good electrical and heat conductivity and creates long spark plug service life
