NGK Spark plugs have been used in all types of race engines throughout the world for many years and are trusted by Vodafone McLaren Mercedes and Ferrari F1 teams and the Qatar M-Sport world rally team to provide the spark for their engines. Designed specifically for race engines, many plugs in the range feature precious metal electrodes such as platinum or gold/palladium for greater durability and lower voltage requirements. Fine wire electrodes provide a better spark, enhanced ignitability, and special insulator noses help improve throttle response.
