NGK B11EGV / 5831 Racing Spark Plug Replaces IW34 IW34

To withstand the severe conditions that occur in racing engines, NGK Racing Spark Plugs feature electrode materials and configurations as follows:

  • Electrode materials - Many use precious metals such as platinum or gold/palladium for greater durability and lower voltage requirements.
  • Electrode configurations - Fine-wire center electrodes provide better sparking and enhanced ignitability. Fine-wire ground electrodes further improve the ignitability of the plug.
  • Insulator configurations - Special configurations are used for the insulator noses to improve throttle response.

  • Height (mm): 85
  • Width (mm): 24
  • Length (mm): 22
  • If you are unsure as to whether this is the correct part for your vehicle, please don't hesitate to contact us. Alternatively please use the cross reference table above.
