The Link O2 Bung and Plug provides a convenient and secure way to install or seal an M18 x 1.5 threaded oxygen sensor port in exhaust systems. Designed to be welded into steel exhaust components, it creates a durable mounting point for wideband oxygen sensors, while the supplied plug allows the port to be sealed when a sensor is not installed.

• Link Wideband O2 Sensor (PN 101-0116)

• Other M18 x 1.5 oxygen sensors

Install the sensor in a suitable location to ensure accurate exhaust gas measurement and avoid excessive heat exposure.
