Stand out with a black ceramic body and a bold red logo/script that give these spark plugs a unique look. ⚡

The insulator is made of 95% pure alumina, providing strong resistance to heat shock and superior electrical insulation.

A multi-rib insulator design eliminates flashover for reliable ignition performance.

Nickel-plated housing prevents oxidation and corrosion to help ensure long-term durability.

Multilayer gaskets and a heat‑crimping process deliver a leak-free, gas-tight fit.

The copper core electrode resists oxidation while offering excellent electrical and thermal conductivity for extended service life.
