Description

The NGK 5238 is a racing spark plug designed for high-performance applications. It features a non-resistor type with a nickel tip and center electrode. The insulator is made of ceramic, and it has a 0.8mm pre-gap size.

Its corrugated ribs prevent flashover, and the pure alumina silicate ceramic insulator provides superior strength and heat transfer. A copper core aids in heat removal, and triple seals prevent leakage.
