NGK Fine Wire Racing Plugs are designed to give you a stronger spark from your existing ignition system. Slightly recessed fine wire iridium center electrode requires less voltage to ionize(jump) the plug gap. This allows a stronger spark which will better ignite the air fuel mixture leading to more power.

  • You can depend on NGK for quality and reliability
  • Requires less voltage to ionize the plug gap
  • Fine wire iridium center electrode
  • Platinum tipped ground electrode
  • Allows a stronger spark
