This 1/2" mild steel bung and plug kit is a shallow-depth weld fitting option for Innovate wideband O2 sensors, offered as an alternative to the standard 1" bung. Choose it for installations that benefit from increased sensor heat exposure or additional clearance between the sensor and surrounding components. It’s a compact, direct-fit option for tight exhaust layouts.
