AEM Universal Wideband UEGO Sensor with Stainless Manifold Bung Kit | AEM 30-2063

Shop the AEM Universal Wideband UEGO O2 Sensor Kit with Stainless Finned Manifold Bung. Factory-calibrated Bosch LSU 4.2 sensor for precise AFR monitoring.

The AEM Universal Wideband UEGO Sensor with Stainless Manifold Bung Install Kit (AEM P/N 30-2063) provides accurate air/fuel ratio (AFR) monitoring for high-performance automotive tuning. At the heart of this kit is a Bosch LSU 4.2 Wideband UEGO sensor, precision-calibrated directly at the Bosch factory to deliver accuracy down to 0.1 AFR. Each sensor features a laser-etched, factory-calibrated resistor integrated into its connector body, eliminating the need for free-air calibration when paired with compatible AEM wideband controllers.

Designed for demanding forced-induction and high-heat exhaust environments, the kit includes a finned stainless steel tall manifold bung. Its stand-off design elevates the sensor tip away from extreme exhaust port heat without obstructing exhaust flow, extending sensor lifespan and maintaining signal integrity. Whether upgrading a single-channel setup or running multi-channel exhaust monitoring, this installation kit provides reliable data for performance tuning.

Best Uses

1. Custom Engine Tuning & Dyno Testing: Ideal for monitoring precise air/fuel ratios on high-performance street, drag, or track vehicles.
2. Individual Port & Multi-Channel AFR Setup: Perfect for multi-cylinder exhaust manifolds where each exhaust runner requires independent O2 sensor monitoring.
3. High-Heat Exhaust Applications: Designed for turbocharged, supercharged, or high-compression naturally aspirated engines running extreme exhaust gas temperatures (EGTs).
4. Replacement/Upgrade Component: Replacement or addition for AEM 4-Channel Wideband UEGO controllers and engine management systems.

Features

1. Bosch LSU 4.2 Wideband UEGO Sensor: Delivers wideband air/fuel ratio monitoring accurate to 0.1 AFR.
2. Factory-Calibrated Connector Resistor: Built-in laser-etched resistor ensures precise sensor factory calibration with zero free-air calibration required.
3. Finned Stainless Steel Tall Bung: Specially engineered stand-off design dissipates heat from the sensor body while keeping exhaust flow unrestricted.
4. Universal Fitment: Designed for weld-in installation on custom exhaust manifolds, downpipes, or individual header runners.
5. Corrosion-Resistant Stainless Steel Construction: Premium stainless steel weld bung resists high thermal cycling and oxidation under heavy track and street conditions.

 Benefits

1. Plug-and-Play Maintenance Free: Eliminates tedious free-air re-calibrations over time, saving installation effort and tuning setup time.
2. Extended Sensor Lifespan: The finned tall bung acts as a heat sink to protect the sensitive ceramic sensor element from heat damage.
3. Uncompromised Exhaust Flow: Stand-off bung design places the sensor element at the proper depth without creating exhaust restriction in narrow manifold ports.
4. Optimized Engine Performance & Safety: Accurate real-time air/fuel data helps prevent lean damage and optimize power output across the entire RPM band.
5. Durable & Thermal-Shock Resistant: High-grade stainless steel construction ensures long-term durability under high-EGT and extreme environment conditions.
