71001 & Hines, 18mm O2 plug wire extension cable

This Vance & Hines O2 sensor extension cable is a practical solution for exhaust installations on 2009 to 2011 Harley-Davidson models equipped with 18mm oxygen sensors. The cable provides an additional 6 inches (15cm) of length, allowing for more flexibility when routing wires to new sensor bung locations on aftermarket headers. It is also a direct replacement for the cable found in the NAMZ 578303 18mm to 12mm O2 bung reducer set. Ensuring your O2 sensors are properly connected without straining the factory wiring harness is crucial for maintaining correct engine management and fuel mapping.
