NGK R6252K-105 Racing Plug

Description

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.
• Ensulator configurations – Special configurations are used for the insulator noses to improve throttle response.
