Product Description
The Accel Performance U-Groove Spark Plugs produce a larger spark for more power at high RPM's. It features a 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. It gives 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. It has 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.

I have used these plugs for many years, and have had nothing but good luck with them.
And when you go by price thse are less price wise than many of the so called top brands like AC delco, autolite ect... And if you have a hot coil or a high preformance ignition system these are a great fit for it. After all ACCEL also makes high voltage ignition systems as well so you can trust these to not burn up like the others might.
