Brisk Projected Iridium Spark Plug (RR14BYIR-7) - 2011-2026 Mustang GT / 2011-2020 Ford F-150 5.0L
Upgrade your ignition system with the Brisk Projected Iridium Spark Plug RR14BYIR-7, engineered specifically for modern, high-output engines that demand reliable performance under demanding conditions. Designed for 2011-2026 Ford Mustang GT models and 2011-2020 Ford F-150 5.0L applications, this premium spark plug delivers consistent ignition, improved cold starts, and dependable combustion whether you're daily driving, towing, or pushing your Coyote-powered vehicle at the track.
Featuring an advanced iridium core center electrode paired with a durable Yttrium alloy ground electrode, this Brisk spark plug requires less ignition voltage than conventional plugs. The reduced voltage demand helps extend ignition coil life while minimizing the risk of misfires caused by oil fouling, prolonged idling, or alternative fuel use. A corrosion-resistant nickel and zinc coating provides long-lasting durability, while the specially designed cylindrical insulator tip promotes rapid self-cleaning shortly after startup to maintain consistent performance throughout its service life.
