GlowShifts Wideband Air/Fuel Ratio Oxygen Sensor Notched Weld-In Bung provides better fitment on the rounded surface of an exhaust system during installation. The curved edge sits flush, making the welding process easier. This wideband bung adapter is designed for 2.5 diameter tubing, but it will easily work with other diameters as well. The result is a seamless and more effective installation of an O2 sensor. Made from high-quality 304 stainless steel, each notched O2 sensor weld bung adapter is 1/2 tall with an 18mm x 1.5mm thread size which is standard for most O2 sensors. At GlowShift Gauges we also back any purchase with unrivaled Customer and Tech Support.
