Brisk Iridium Performance P3 Spark Plug ER15YIR-1 (2015–2023 Hellcat)

Long-Life Performance Upgrade for Hellcat Engines

The Brisk Iridium Performance P3 ER15YIR-1 Spark Plug is a premium upgrade for 2015–2023 Dodge Challenger and Charger Hellcat models. Designed as a direct replacement for OEM plugs, this spark plug delivers enhanced ignition efficiency, extended service life, and improved overall performance.

Iridium Core for Maximum Durability

Featuring a 0.8mm iridium center electrode, this plug offers exceptional resistance to wear and spark gap erosion. Iridium’s durability allows for extended service intervals up to 65,000 miles, making it an ideal solution for long-term performance and reliability.

Advanced Electrode Design for Improved Ignition

The combination of an iridium center electrode and a yttrium alloy ground strap with copper core enhances spark efficiency while reducing required ignition voltage. This results in easier starts, improved combustion, and reduced strain on ignition components.

Power Focus & Flash-Over Suppression

Designed with power focus technology and flash-over suppression, this spark plug ensures consistent spark delivery even under demanding conditions. It also improves flame kernel development for better combustion efficiency.

Improved Engine Efficiency & Component Life

Lower ignition voltage requirements help extend the life of ignition coils, wires, and modules. The optimized spark exposure reduces flame quenching, especially during cold starts, leading to smoother operation and better fuel efficiency.
