NGK SPARK PLUG LR8B 6208 452390-93000

NGK Spark Plug LR8B

The NGK Spark Plug LR8B is engineered for superior ignition performance and durability. Featuring NGK's advanced wide heat range technology, this spark plug utilizes a copper wire core that offers faster heat dissipation compared to conventional iron cores. This rapid cooling of the electrode and insulator tip contributes to a higher pre-ignition rating.

Built with high-conduction copper and a long-nose insulator, the LR8B ensures efficient heat transfer and robust performance. The corrugated ribs are designed to prevent flashover, maintaining consistent spark delivery. NGK's commitment to quality is evident in the use of pure alumina silicate in the ceramic insulator, providing exceptional strength and improved thermal conductivity.

This spark plug includes a copper core and a triple-seal construction to further enhance heat dissipation and prevent internal leakage. It is specifically designed to meet the demands of high-performance engines, offering an extended lifespan and optimal operational efficiency. Each spark plug is sold individually.
