Brisk ER14YS Silver Racing Spark Plug – 1 Heat Range Colder Street (2015–2023 Hellcat)

Street-Friendly Performance Upgrade for Hellcat Engines

The Brisk ER14YS Silver Racing Spark Plug is designed for 2015–2023 Dodge Challenger and Charger Hellcat owners looking for improved ignition performance with a 1 heat range colder design. This plug is ideal for street-driven vehicles with mild performance upgrades, offering a perfect balance of power, drivability, and reliability.

Silver Core Technology for Maximum Spark Efficiency

Featuring a 1.5mm fine wire silver center electrode, the ER14YS provides unmatched electrical and thermal conductivity. Silver produces a stronger, more consistent spark compared to traditional materials, improving combustion efficiency and overall engine response.

Optimized for Street & Mild Performance Builds

With a projected tip and slightly colder heat range, this plug is perfect for tuned Hellcats, pulley upgrades, and lightly modified setups. It maintains excellent idle quality while offering added protection against heat in higher performance conditions.

Advanced Electrode Design for Better Combustion

The cut-back ground electrode increases spark exposure to the air/fuel mixture, allowing for faster flame propagation and improved combustion efficiency. This results in better throttle response and smoother power delivery.

Improved Ignition & Component Longevity

Thanks to its low ignition voltage requirements, the ER14YS reduces stress on ignition coils while maintaining reliable spark even under demanding conditions. It also provides excellent resistance to fouling during both light and heavy load operation.
