Z1 Motorsports Oxygen Sensor Extension Bungs for all ODB II equipped vehicles, including the 1996 300zx and all 350Z, G35, G37 and 370Z models.

These Extension Bungs are strongly suggested when upgrading to Test Pipes or when the catalytic converters are removed in order to deter the Check Engine Light from coming on.  While this isn’t a guaranteed fix it has been seen to work in most cases. The primary function of the Extension Bungs is to move the downstream oxygen sensors, after the catalytic converters, out of the direct exhaust stream. Moving the O2 sensors out often “tricks” the ecu into thinking a catalytic converter is still in place. However, this isn’t guaranteeded to work but has proven to be successful in most cases.

The Z1 Motorsports Extension Bungs will fit all standard oxygen sensors and exhaust bungs. 

To install the extension bungs, a 22mm wrench is needed. The same wrench that is needed to install the oxygen sensors themselves.

Questions our customers have asked...


What size - mm - are the bungs. i am trying to put a later model 17mm bung into the existing 22 mm O2 bung hole. And will this work ? I probably will also need the 17mm O2 sensor if u have them. The car is an 85 Z31 Turbo. I have replaced the original engine with an 88W turbo engine ecu, injectors and need to use the later model o2 sensor..

Response: These are threaded M18X1.5 like most late model O2 Sensors.
