ACCEL 0762 U-Groove Spark Plug , Pack of 1
The Accel U-Groove Spark Plugs produce a larger spark for more power at high RPMs. They improve throttle response and fuel economy, and reduce fouling. The hottest feature of these spark plugs are the unique U-Groove ground electrode. This specially design electrode was developed to meet the demand for improved ignitability and increased fuel combustion. The U-Groove design results in less flame dissipation. This 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. With the U-Groove ground electrode, firing can be greatly improved without increasing the spark gap. ACCEL 0762 U-Groove Spark Plug , Pack of 1 Increase in performance with improved throttle response. Their purified Alumina insulator prevents arcing, and their machine-rolled threads protect heads.
