AEM 30-4008 Universal Stainless Steel Tall Wideband UEGO Sensor Bung Install Kit

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. Finned for Added Cooling - Ideal for Turbo Applications

• Tall design enhances sensor cooling and minimizes restriction
• Finned design enhances cooling
• Ideal for boosted applications
• Stainless steel construction

The AEM 30-4008 Universal Stainless Steel Tall Wideband UEGO Sensor Bung Install Kit is designed for forced-induction applications using the AEM 4-Channel Wideband UEGO Controller. It is also suitable for wideband oxygen sensors on a broad range of vehicles and works with AEM wideband UEGO air-fuel-ratio controllers. This installation bung provides a secure mounting point while helping protect the sensor from excessive exhaust heat.

Its tall profile keeps more of the sensor body away from the hottest areas of the exhaust stream and minimizes how far the sensor tip extends into the exhaust piping. This design helps reduce flow restriction while supporting reliable sensor operation. Integrated cooling fins further improve heat dissipation, making the AEM 30-4008 a practical choice for turbocharged and other boosted applications. Constructed from stainless steel, the bung is built to withstand demanding exhaust-system conditions.

• Ideal for turbocharged and boosted applications
• Compatible with AEM wideband UEGO sensors and controllers
• Universal design supports installation on a wide range of vehicles
• Recommended for use with the AEM 4-Channel Wideband UEGO Controller
