Here we have a high quality stainless steel oxygen sensor exhaust bung with a stepped edge which makes them easier to install. The Spartan kits do not include a bung, as most people already have them in their exhausts. But there will be some customers that are wanting to run multiple wideband’s and need extra bungs, and people that want to keep their original narrowband sensor and need an oxygen sensor exhaust bung for their wideband.
These are compatible with all oxygen sensors, for those wondering on the thread type of the 02 bung, here they are for you, M18 x 1.5mm
