Spark Plug Iridium Performance

With very long lifespan, the P range Brisk spark plugs are the most modern design to fit modern highly efficient and stressed engines. The Iridium core center electrode is surrounded by a Yttrium alloy made body and earth electrode that gives very low voltage requirement prolonging ignition coil lifespan. Lower voltage requirement stands for easier cold starts, less of a chance of a misfire due to fouling as a result of oil burning, use of alternative fuels or prolonged idling. One heat range colder than the factory plug that is a direct replacement for the NGK-6510. The RR14BYIR-7 has been optimized for forced induction use as it comes with a beefier insulator and fine wire construction. This plug offers outstanding performance and provides a longer lifespan than the current RR14YS.
