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 gapable 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.
Features:
The Copper core is a better conductor than Iridium or Platinum plugs
Copper dissipates heat much better than other materials
"C" - Cut Design un-shrouds the spark kernel for a better burn
Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
Machine rolled threads for precise thread engagement

Whether using on the street or on the strip, ACCEL HP Copper Core spark plugs deliver!
