Wideband Air/Fuel Ratio Oxygen Sensor Weld-In Saddle Bung

GlowShift Stainless Steel Weld-In Saddle Bungs give you the ability to install an oxygen sensor to your car or truck’s exhaust. Each weld in bung is cast from 304 stainless steel with a rounded, saddle-style shape, making it easier to mount and weld to the exhaust tube. It works best on larger tube sizes with 2.5” and 3” diameters. With this design you’re also not welding near the threads which can sometimes cause them to warp. Once the stainless steel bung adapter is in place you’ll be able to install any M18 x 1.5 oxygen sensor. GlowShift includes Free Lifetime Tech Support and a One Year Limited Warranty with each O2 sensor bung purchase.
