HKS Super Fire Racing Spark Plug

The HKS Super Fire Racing M45HL Spark Plug is a high-performance ignition upgrade designed to deliver stronger, more consistent spark. It offers improved ignition efficiency, durability, and reliability in high-heat, high-load environments, suitable for both modified and stock-performance applications.

The plug features a 0.6mm iridium alloy center electrode to reduce required voltage and enhance spark intensity, along with a platinum-chip outer electrode for improved durability and long-term performance. Additional features include a short-type outer electrode with an anti-vibration design, a Thermal Edge design to help reduce carbon deposits, and a Spark Support Gap to prevent carbon buildup and misfires.
