O2 Sensor Bung, Stainless Steel Oxygen Sensor Mounting Bungs and Plugs, M18 X 1.5 Thread Notched Style Oxygen Sensor Fitting Bungs, Suitable for 1.5-2 inch Pipe- 2 Bungs/2 Plugs

Worked perfect when I was installing new exhaust on my 97 Ram 1500 with the 5.9 Magnum. Very good value for the money. Fit was perfect. The curve fit my 3” piping perfectly.

Very good quality part. Weld up nicely.

After tossing the stock exhaust manifolds for some headers, I needed to build new downpipes to mate the catalytic converters and header collectors. These mounting bungs came with a perfect cope to match my pipe diameter and even came with stainless plugs to keep weld slag out of the threads WHILE helping to center the O2 sensor location within the pilot hole. Definitely recommend picking these up to help with your next exhaust project!

Nicely price & it works

Worked just as it should glad they were able to work out for my build.

Did the job

Ordered item but instead of four sets ( 2 bungs & 4 plugs) only 2 bungs and 2 plugs were in the package. Items are excellent but we only got half of what we ordered. Will contact Amazon to rectify.

i use these on all the downpipes i build, great quality and they weld up great.

Worked

As expected great item

Good
