U-Groove performance spark plugs have a patented U-shape cut into the ground electrode that produces a double wide, hot spark to ignite standard or even high compression engines. The sintered alumina heavy-duty five rib insulator eliminates flashover and overheating that occurs with high performance and long range applications. Accel U-Groove spark plugs use the purest copper/nickel alloy electrode to produce a broad heat range that is highly foul-resistant and dissipates heat better than any other material. Racing and street performance has proven that U-Groove spark plugs deliver hot spark and high performance.
