Description Technical Specs
NGK racing spark plugs are built to withstand the severe mechanical and thermal shock associated with high-revving, high-compression engines.

Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. And, the unique arrangement of insulator noses improves throttle response!
