Accel U-Groove Spark Plugs For Harley Twin Cam And Sportster

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.


  • Accel's state-of-the-art, U-Groove spark plugs with ground electrodes, copper glass inner seal and electric heat seal prevent leakage in high-compression engines
  • Permit the spark to develop a larger, fuller flash for a more complete burn
  • Sold in pairs
