Brisk ER15YS Silver Racing Spark Plug – Stock Heat Range (2015–2023 Hellcat)

High-Performance Replacement for Factory Hellcat Spark Plugs

The Brisk ER15YS Silver Racing Spark Plug is a premium upgrade designed for 2015–2023 Dodge Challenger and Charger Hellcat applications. Featuring a stock heat range, this plug is ideal for maintaining OEM drivability while improving ignition performance and efficiency.

Silver Core Technology for Superior Ignition

Utilizing a silver center electrode, the ER15YS delivers unmatched electrical and thermal conductivity. Silver outperforms traditional materials like iridium and copper, resulting in a stronger spark, better combustion, and improved engine responsiveness.

Optimized for Street & Performance Use

With a projected tip design and stock heat range, this spark plug is perfectly suited for both daily driving and performance applications. It provides smooth idle quality, consistent throttle response, and reliable operation under a wide range of conditions.

Advanced Electrode Design

The cut-back ground electrode enhances spark exposure to the air/fuel mixture, promoting faster flame propagation and more efficient combustion. This results in improved performance and reduced misfires, especially under load.

Direct Replacement Upgrade

The ER15YS is a direct replacement for OEM spark plugs such as PLZFR6A11S and FR5, making it an easy upgrade for Hellcat owners looking to improve ignition performance without changing heat range.
