BBK O2 Sensor Wiring Extension Kit

2015–2023 Dodge Challenger / Charger 6.2L SRT Hellcat

Part #: 1114

Overview

The BBK O2 Sensor Wiring Extension Kit is an essential upgrade for owners of 2015 to 2023 Dodge Challenger and Charger models equipped with the 6.2L SRT Hellcat engine who are installing full-length headers. When upgrading to full-length headers, the factory oxygen sensor locations are relocated, making the stock wiring harness too short to reach the new sensor positions. This kit provides a clean, reliable solution by extending the wiring harness without cutting or splicing into the factory wiring.

Designed specifically for the front oxygen sensors, the BBK extension kit ensures a seamless, factory-like connection that maintains the integrity of your vehicle’s electrical system. It is ideal for enthusiasts seeking a professional installation that preserves the original wiring harness and avoids potential wiring damage or signal issues.
