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.
