AEM/30-4005 - Mild Steel O2 Sensor Bung
AEM's mild-steel wideband UEGO air/fuel ratio sensor bung is an economical solution for providing a sensor mount when installing a wideband UEGO AFR sensor in your exhaust. This bung must be welded into your exhaust system. For a more robust mounting solution please review our stainless steel wideband UEGO air/fuel ratio sensor bungs. This bung has an M18 x1.5 thread pitch.

AEM/30-4008 / AEM/30-4008-4PK (4 Pack) - Stainless Steel O2 Sensor Bung
AEM's stainless-steel tall wideband UEGO sensor bungs are designed specifically for use on forced induction applications using the 4-Channel Wideband UEGO Controller, but can be used for wideband sensors on any vehicle and with any AEM wideband UEGO AFR controller. The tall design of the bung keeps the sensor body cool and reduces restriction by minimizing the intrusion of the sensor tip into the exhaust piping, and the finned design enhances cooling.
