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.
