      High Powered Performance. Don't replace your EcoBoost Mustangs old spark plugs, upgrade them!
      Brisk Silver Racing Spark Plugs are the perfect performance upgrade for EcoBoost Mustangs that have lost power due to fouled or damaged plugs. It is highly recommended to change your old spark plugs every 30,000 to 45,000 miles as part of your Mustangs routine maintenance.

      Superior Design and Materials. Brisk Silver Racing spark plugs feature a high dielectric strength insulator and use a 1.5mm fine wire silver center electrode for its excellent electrical and thermal conductivity which in turn produces a more powerful spark. The tapered ground strap design allows for superior ignitability on hard to ignite fuels minimizing the chance fouling.

      Application. This set of four (4) Brisk Silver Racing Spark Plugs are specifically designed for the 2015 to 2023 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-Cylinder engine.

      Technical Note. These Spark Plugs are ideal to be used on a Non-Modified/Stock EcoBoost Mustang. If your planning on modifying the vehicle, especially with a tune, it would be best to get a non-projected spark plug like Brisk's part# RR14S or a colder heat range spark plug like Brisk's part# RR12YS.
