Brisk's Extra Turbo Racing Spark Plugs are designed for performance and racing applications that undergo wide open throttle conditions for long periods of time and have extreme cylinder pressures due to use of forced induction, nitrous or endurance style racing. Extra turbo racing spark plugs eliminate the erosion of the spark plug gap which typically wears down causing misfires under high load or peak pressures, making these an ideal solution for applications occurring these issues. Extra turbo racing spark plugs reduce the number of imperfectly ignited cycles, delivering high durability and reliability for racing environments.
