Description

The NGK R5724-9 is a racing spark plug designed to withstand severe mechanical and thermal shock from high-revving, high-compression engines. It features special electrode materials for durability and low voltage requirements, with fine-wire center and ground electrodes for better sparking and ignitability. The unique arrangement of insulator noses also improves throttle response.
