ACCEL U-Groove Resistor Race Plug, .035inch Nomial Gap Spark Plug

One of the hottest features of this Accel spark plugsis its unique U-Groove ground electrode. This specially design electrode was developed to meet the demand for improved ignitability and increased fuel combustion. The Accel 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. Effectively, it produces greater firing energy. On the other hand, conventional plugs squash the flame. This is called ''quenching effect'' and leads to spark plug misfire and rough idle. This has a negative effect on the spark. With the Accel U-Groove ground electrode, firing can be greatly improved without increasing the spark gap. The U-Groove ground electrode also 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
