Description

The NGK SILMAR8A9S is a Laser Iridium spark plug designed for high-performance applications. It features a fine wire iridium-tipped center electrode and a fine wire platinum-tipped ground electrode, contributing to a slow wear rate, stable idle, and improved fuel efficiency.

The spark plug is constructed with a pure alumina silicate ceramic insulator for superior strength and heat transfer, a copper core for heat removal, and triple seals to prevent leakage. Its trivalent metal plating offers enhanced anti-corrosion and anti-seizing properties.
