ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL HP Spark Plugs are capable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.

Product Features:

• Designed with a copper core for superior conductivity, ensuring optimal performance in high-combustion pressure environments.
• Exceptional heat dissipation properties reduce the risk of misfires, enhancing reliability and efficiency.
• Gapable design allows for customization, enabling adjustments for larger flame kernels or high-boost applications.
• Precision-engineered machine-rolled threads provide accurate thread engagement and improved torque retention.
• Tapered seat type ensures a secure fit and optimal sealing for consistent performance.
