Brisk has released a new offering in their Iridium Performance P+ line for the Coyote, Hemi and LT1/LT4 Applications.
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.
Note: Plugs are sold individually.
