This Kooks set of oxygen sensor extension harnesses is designed to provide proper length and secure connectivity for O2 sensors on 2019–2020 Ram 1500 SXT trucks.
These extensions are engineered for applications requiring additional wiring length when installing long tube headers or modified exhaust systems. Built with OEM-style connectors and heat-resistant wiring, they ensure consistent performance and durability under demanding conditions. The plug-and-play design eliminates the need for cutting or splicing, maintaining factory wiring integrity while preventing check engine lights caused by poor sensor communication.
