Description

The NGK LKAR8BI-9 is a Laser Iridium spark plug designed for performance enthusiasts. It features a fine wire center electrode made of an iridium alloy for high durability and a stable spark, ideal for high-tech engines. The plug is constructed with a pure alumina silicate ceramic insulator for strength and heat transfer, a copper core for heat removal, and triple seals to prevent leakage.

Additional features include trivalent metal plating for anti-corrosion and anti-seizing properties, and corrugated ribs to prevent flashover. The spark plug has a thread diameter of 12mm, a 1.25mm thread pitch, and a 26.5mm reach. It also includes a resistor with a value of 5k Ohm.
