Product Description

Z1 Exhaust Bung Plugs are great for use where factory sensors have been removed, and un-used exhaust bungs are present. Z1 Exhaust bungs are zinc coated for maximum corrosion resistance, and are ideal for any exhaust component that utilizes an M18x1.5 exhaust bung. (example: all Nissan and Infiniti Oxygen Sensor bungs)

Please Note: we have multiple types in stock, you may receive either a gold or silver zinc bung plug.


Due to the availability and condition of these parts, all liquidation items are sold "as is" and cannot be returned for any reason. Z1 offers several blemished / overstock items at a substantial discount in our Clearance Categories.

I bought this to plug the factory O2 sensor location when I installed a relocation kit, the fitment was perfect and no leaks.
