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.
