3:Stainless Steel Wideband O2 Bung description

Wideband Weld-In Bung is being extended 1" versus the standard 1/2” bung, the length and design allows oxygen sensor to sit flush with exhaust causing less restriction and also extends the life of the sensor by allowing less exhaust temperature exposure. The overall result is a seamless and more effective installation of O2 sensor, which can be extremely beneficial in a wide range of uses including high horsepower applications. Made from high-quality 304 stainless steel, this wideband o2 bung has a thread size of 18mm x 1.5mm which is standard with most oxygen sensors.
