Description

The NGK LTR6DI-8 is a laser iridium spark plug designed for performance enthusiasts. It features a fine wire iridium center electrode for high durability and a stable spark, along with a platinum ground electrode. The plug has a 14mm thread diameter, 1.25mm thread pitch, and a 25mm reach.

Constructed with a pure alumina silicate ceramic insulator for strength and heat transfer, it also includes a copper core for heat removal and triple seals to prevent leakage. The trivalent metal plating offers superior anti-corrosion and anti-seizing properties, while corrugated ribs prevent flashover. This spark plug has a heat range of 6 and a projected gap of 0.031 inches (0.8mm).
