Product Details

This is a Stainless Works O2 Bung, a small but important piece for custom exhaust setups or when modifying your exhaust system. It gives you a clean, threaded port to install an oxygen sensor, which is crucial for your engine's computer to monitor emissions and fuel mixture.

This particular bung is CNC machined from 304 stainless steel, which is a solid choice for exhaust components because it holds up well to heat and corrosion. It features M18 x 1-1/2" threads and has a lead-in chamfer, making it easier to thread your O2 sensor in without cross-threading. The overall height is 1/2 inch, so it won't take up too much space in your exhaust pipe.

When you're installing this, the manufacturer recommends using anti-seize on the O2 sensor threads to make sure it comes out easily later. This bung is made in the U.S.A. and comes with a lifetime warranty.
