SPARK PLUGS 75-99BT (MID)

SPARK PLUGS 75-99BT (MID)

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
