Accel Spark Plugs

Accel Spark Plugs put more fire in the hole, so you get more power to the wheels! Accel U-Groove spark plugs are made with a performance enhancing U-shaped groove in the electorde. This specially designed electrode was developed to meet the demand for improved ignitability and increased fuel combustion. The U-groove of the ground electrode results in less flame dissipation. It also 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, while conventional plugs tend to squash the flame. This is the U-Groove performance advantage.
