• Manufactured from the best materials available for long, trouble-free operation
  • The premium quality platinum tip is more durable than standard plug material so the spark plug will maintain the proper gap much longer
  • The pure copper center electrode reduces fouling
  • The proper spark plug gap requires less voltage to fire so you will have fewer misfires for long periods of use
  • Easier starting, improved fuel economy, smooth idling and quicker acceleration are just a few benefits of Accel platinum spark plugs
Key Features:
  • Platinum Tip Center Electrode: Bonded to massive copper core for superior conductivity and power
  • U-Groove Ground Electrode: Develops a larger spark for more complete combustion
  • Insulator and Five Rib Construction: Insulator made of highly purified alumina powder - superior in strength and thermal conductivity
  • Copper-Glass Seal: Glass and copper powder bond the center electrode to the insulator by electroforming process to assure a gas tight seal
  • Elecric Heat Seal: Seals tighter for a stable heat range
  • Machine Rolled Threads: For trouble-free spark plug installation and removal
