The o2 oxygen sensor mounting bungs is easy to weld on exhaust, headers, down pipes, etc.
The exhaust bung plug set features a straight thread size of M18*1.5 mm, which is suitable for most vehicles.
Install the weld bungs to replace or add oxygen sensor ports to any OEM or aftermarket exhaust or downpipe. Drill a hole and weld the wideband bung on.
The bung cap can be used to seal O2 sensor bungs that are not being used in the exhaust system. The gasket helps create a tight seal to prevent any exhaust leaks. (Note: If the gasket you received is not flat, please be assured that it does not affect the use)
The M18*1.5 bung features a stepped design, allows for an easy fit.
