2015-2023 Mustang 2.3 Brisk Silver Racing Spark Plug Kit - Projected Tip
Maximize the performance of your engine modifications with this 2015-2023 Mustang EcoBoost spark plug kit! This Brisk Silver Racing spark plug kit is designed for EcoBoost owners that have bolt on modifications and daily or frequently drive their Mustang. The heat range is one step colder compared to stock and features a silver electrode that transfers electricity and heat better than any other plug material! This results in the most powerful spark for combustion efficiency and horsepower gain.

Super Conductor
Brisk Silver Racing spark plugs feature a silver electrode that is the best conductor of thermal heat and electricity. Silver conducts 560% more electricity and 481% more heat compared to Platinum plugs. This design is beneficial when your stock ignition system is pushed to the limit and eliminates the need to upgrade. This plug requires lower supplied ignition voltage which is beneficial to cold starts and supercharged, turbocharged, or nitrous injected engines. Silver has been found to be the best conductor to ignite fuels such as premium gasoline, E85, Alcohol, Propane, and others.

Additional Features

  • Nickel/Zinc Coating Provides Superior Corrosion Protection.
  • The space between the reduced diameter of the center electrode and the insulator tip enables fast evaporation of fuel and prevents the formation of soft combustion deposits on the insulator tip of the spark plug.
  • The cylindrical ending of the spark plug insulator tip enables the very fast achievement of spark plug self-cleaning temperature after engine start.
  • The ceramics mass with high content of AI2O3 with an increased dielectric strength of the spark plug.
  • The copper core of the center electrode increases the thermal conductivity and therefore it enables the insulator tip elongation by sufficient thermal value reserve of spark plug.
