The Accel Performance U-Groove Spark Plugs produce a larger spark for more power at high RPM. They feature an unique U-Groove ground electrode that develops larger spark nucleus for improved combustion and reduced fouling. The U-Groove design results in less flame dissipation. These give the flame a groove to grow in, creating a larger flame front for a more complete combustion even in the case of lean air/fuel mixture. They have a larger spark nucleus which stimulates faster combustion, producing more power for higher RPM's of longer duration. The end result is an increase in performance with improved throttle response and, due to a more complete burn, greater fuel efficiency and reduced emissions. Five-Ribe, highly purified Alumina insulator provides superior strength and thermal conductivity. It also prevents arcing at plug boot. The electric heat seal ensures stable heat range for uniform performance and copper glass seal bonds insulator to electrode for a gas-tight seal.
