Wideband Air Fuel Ratio Gauges are key for calibrating your engine and monitoring your AFR to optimize the performance of your car or truck. When you’re looking to add one of these gauges to your vehicle, we can help ensure that your wideband O2 sensor is installed securely.

Our Wideband Air Fuel Ratio Oxygen Sensor Weld-In Saddle Bung makes the installation process easier and enables a better and more reliable placement for the oxygen sensor, giving you extremely accurate readings directly from your vehicle’s exhaust.

This O2 sensor bung is equipped with an M18 X 1.5 Thread so you can install any M18 x 1.5 wideband oxygen sensor. It also has a rounded, saddle-style shape so that it matches the contour of your car or truck’s exhaust tube, working best on larger tube sizes with 2.5” and 3” diameters.

We made sure this weld in bung was extremely tough and durable, and had it cast from 304 stainless steel. That way once it’s installed, it’s not going anywhere and it’ll get the job done for your O2 sensor. By incorporating a weld-in friendly design, you also won’t be welding near the threads which can sometimes cause them to warp.

So when it’s time to install a Wideband AFR Gauge to your vehicle, go with one of our wideband oxygen sensor stainless steel bung adapters and make installation easier. This weld-in saddle bung will effectively bridge your access to reliable AFR readings that will help you get better performance out of your car or truck.
