Brisk Iridium/Yttrium Spark Plug

The Brisk RR14BYIR-7 spark plug is engineered with advanced materials for enhanced engine performance and longevity. It utilizes an Iridium core for the center electrode, complemented by a Yttrium alloy for the body and ground electrode. This combination offers a very long service life, extending up to 100,000 km or 60,000 miles, making it a durable choice for demanding applications. One of the key benefits of the RR14BYIR-7 is its significantly lower voltage requirement. This is achieved through the Yttrium alloy construction, which helps prolong the lifespan of ignition coils. The reduced voltage demand contributes to easier cold starts, minimizes the likelihood of misfires caused by fouling (whether from oil burning, alternative fuels, or prolonged idling), and generally supports more efficient combustion. Its features include nickel/zinc coating for corrosion protection and a projected tip design. Key specifications include a 14mm thread diameter, a 25mm (1-inch) thread reach, a 16mm (5/8-inch) hexagon for wrench fitment, and a tapered seat. The design is Iridium/Yttrium, it includes a resistor, and it features a projected tip. The heat range is rated at 14. Popular applications include the Ford Mustang 5.0 Coyote, Chevy LT1/LT4/LSA, Dodge HEMI Engines 6.1/6.4L, Dodge SRT 4, Chrysler 300, Chevy Cobalt SS, Saturn ION Redline, Chrysler PT Cruiser, and Ford Focus.
