Accel Spark Plugs

Accel U-Groove Spark Plugs were leaders in the industry almost thirty years. This patented technology enabled the spark plug to create a hotter, fuller flash front for a more complete "burn" in combustion chambers. Now that fuel management and cylinder heads have evolved, so have Accel Spark Plugs. These revised 1-piece spark plugs feature conventional ground electrodes, machine-rolled threads to protect heads, and purified Alumina insulators to prevent arcing.
