Brisk YTE Spark Plugs offer 3 Electrodes, extending the life span and durability of the spark plug. YTE Spark Plugs provide Open Fire Technology where the spark plug gaps are open for the air-fuel mixture to reach the spark, and for the flame to grow into the combustion chamber more rapidly and with less restriction. The 3 electrodes have a shorter path for heat to dissipate into the spark plug shell and into the cylinder head resulting in a cooler system. These spark plugs are an ideal choice for daily driven vehicles where slightly better fuel economy and gas mileage is desired, as well as for performance-oriented applications, such as street performance, spec racing, and stock racing.
