NGK SILMAR8A9S Laser Iridium Spark Plug - 90992

Upgrade your engine's performance with the NGK Laser Iridium Spark Plug. Known for their exceptional quality and durability, NGK spark plugs deliver reliable ignition and optimized combustion for a wide range of applications.

Description

The NGK Laser Iridium Spark Plug features a fine wire iridium center electrode and a specially designed ground electrode to ensure a focused spark and efficient burning of fuel. Trivalent metal plating eliminates the need for anti-seize compounds and offers superior anti-corrosion properties. Its pure alumina silicate ceramic insulator enhances dielectric strength and heat transfer. A copper core dissipates heat quickly, preventing pre-ignition and fouling. Triple seals prevent combustion leakage. This spark plug is designed to withstand the rigors of modern, high-performance engines.
