Stainless O2 Sensor Heatsink Bung Exhaust Fitting: L3 S20 S40 SOHCAEM'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.
