Brisk ER10S Silver Racing Spark Plug – 3 Heat Range Colder (2015–2023 Hellcat)

Extreme Cooling for High-Horsepower Hellcat Builds

The Brisk ER10S Silver Racing Spark Plug is designed for 2015–2023 Dodge Challenger and Charger Hellcat platforms running extreme performance setups. Featuring a 3 heat ranges colder design, this plug is ideal for high-boost, high-compression, and race-focused applications where maximum heat control is critical.

Silver Core Technology for Maximum Spark Energy

Built with a 1.5mm fine wire silver center electrode, the ER10S delivers unmatched conductivity. Silver is the best electrical and thermal conductor of any metal, providing a stronger spark, improved combustion, and superior heat dissipation compared to traditional materials.

Built for Extreme Performance Applications

This racing spark plug is engineered for high boost supercharged setups, turbocharged combinations, nitrous systems, and ethanol/methanol fuel applications. Its colder heat range helps prevent detonation and pre-ignition in engines pushing the limits of performance.

Advanced Racing Electrode Design

The non-projected tip and cut-back ground electrode improve spark exposure and flame front propagation. This ensures faster, more efficient combustion while maintaining reliability under extreme cylinder pressures.

Improved Ignition Efficiency & Component Longevity

With lower ignition voltage requirements, the ER10S reduces stress on ignition coils while maintaining consistent spark under harsh conditions. It also offers excellent resistance to fouling and stable operation at high RPM.
