Product Overview
Overview:
The NGK BU8H (6431) Standard Spark Plug is a high-performance surface gap spark plug designed for specific high-compression applications. Known for being nearly immune to pre-ignition, this spark plug is ideal for use with specialized high-energy ignition systems. While it can be susceptible to fouling in colder environments, it remains a necessary choice for high compression setups. Featuring trivalent metal plating for superior anti-corrosion and anti-seizing properties, along with corrugated ribs to prevent flashover, the NGK BU8H offers long-lasting, reliable performance. Its pure alumina silicate ceramic insulator provides superior strength and better heat transfer, while the copper core efficiently removes heat, ensuring optimal operation. The triple seals on this spark plug help prevent leakage for improved engine performance.
