2011-2023 Mustang Brisk Iridum Spark Plugs - Projected Tip
Restore the performance of your 2011-2023 Mustang 5.0 with these Brisk 1-step colder Iridium spark plug kit! This kit includes six new spark plugs that have a lower required ignition voltage for easier starts. The iridium plug features an extremely durable material that extends the spark plug lifetime by reducing spark plug gap erosion. These Brisk USA spark plugs utilize dual copper core electrodes for increased energy. The plug's copper core ground electrode provides better heat dissipation from the ground strap which reduces temperature by around 212 degrees! This reduces the chance of pre-ignition detonation and burn-off which extends the service life of the plug.

Projected Tip vs. Non-Projected Tip Spark Plugs 
Spark plug projection is simply the distance from the end of the metal shell to the center electrode's tip. Projected-tip spark plugs are great for fairly mild/street/low boost setups. Typically around 6-10psi or 300-600 horsepower. When it comes to high boost, high amounts of timing, or race fuel, a non-projected spark plug may be the answer. The high heat created by the combustion process in high horsepower engines can cause the ground strap to melt off of the spark plug, resulting in misfires or pre-ignition. On non-projected tip spark plugs, the grounding strap is closer to the threaded body. This allows heat on the grounding strap to be dissipated to the spark plug threads and cylinder head, preventing the strap from melting off. Always be sure to consult your tuner if you are unsure of the best spark plug type for your application.

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 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.

About This Brand


Brisk USA
For 82 years, Brisk has carried a tradition of being the best. Despite of claims, there is no other spark plug manufacturer in the world that offers a spark plug with multiple discharges per single ignition system impulse! Brisk covers virtually all customer requirements for a better performing spark plug! Whether its life longevity and low-cost spark plugs for your every day drivers or maximum efficiency and durability in a more specific, high-performance application, Brisk has the ideal solution for your needs. Brisk has played a major role in some of the world's record-holding passes and builds in the Performance and Racing Industry, providing a spark plug that creates more horsepower and can fire under extreme cylinder pressures. The most prominent example of this is the Ford Modular 3-Valve platform spark plug replacement. Brisk was the first in the world to offer a single piece spark plug billet design to eliminate the factory spark plugs from breaking off in the engine cylinder head.
