When you install a header on your Subaru engine the O2 sensor can move locations and this create tension on the harness, or it may no longer reach. Our Front O2 Extension Harness extends the front O2 sensor wiring to accommodate the new O2 sensor location. This is typically for WRX engines because of the design of the intake manifold harness.
Our extension harness is 12 inches long and built with high quality materials including tefzel wiring and raychem sleeving. It also includes a ground terminal to ensure the Front O2 Sensor works properly.
