AEM FAE Wideband Uego Replacement Sensor

AEM FAE Wideband UEGO Replacement O2 Sensor | 30-2404

Replace or upgrade your AEM X-Series wideband gauge sensor with the AEM FAE UEGO replacement sensor (PN 30-2404). Features faster response times and enhanced thermal durability.

Restore total precision to your engine tuning with the AEM FAE Wideband UEGO Replacement Sensor. Engineered as a rugged, high-performance upgrade over standard wideband sensors, the FAE sensor delivers faster sampling rates and increased thermal endurance, making it built to survive the harsh environment of high-output engines.

Designed specifically for seamless integration with AEM X-Series UEGO Controller Gauges (PN 30-0300), this replacement wideband O2 sensor utilizes an integrated, factory-calibrated trim resistor built directly into the connector. This allows for plug-and-play installation without the hassle of manual free-air calibration. Whether you are running pump gasoline, leaded race fuel, or high-octane ethanol blends, the AEM FAE sensor delivers accurate Air/Fuel Ratio (AFR) and Lambda feedback to protect your engine and maximize horsepower.

Best Uses

1. Replacing Worn or Damaged Sensors: Direct replacement O2 sensor for AEM X-Series wideband AFR gauges.
2. High-Performance & Race Engines: Monitoring air/fuel ratios on turbocharged, supercharged, or high-compression naturally aspirated builds.
3. Multi-Fuel Applications: Tuning vehicles running on unleaded gasoline, leaded race fuels, E85, or methanol.
4. Dyno & Street Tuning: Real-time feedback for ECU mapping, closed-loop fuel control, and stand-alone engine management systems.

Features

1. Factory Trim Resistor Calibration: Includes an internal, precision-trimmed resistor built into the connector housing, eliminating required free-air calibration upon install.
2. Enhanced Thermal & Chemical Resistance: Constructed with advanced ceramic sensing elements designed to withstand harsh exhaust gas temperatures and harsh fuel additives.
3. Faster Response Times: Delivers an approximate 10% faster response time compared to standard Bosch LSU 4.9 sensors for quicker AFR readings.
4. Wide Fuel Compatibility: Fully compatible with unleaded gasoline, leaded race gas, diesel, E85, ethanol, and methanol fuels.
5. Direct Plug-and-Play Wiring: Pre-terminated harness connector designed for direct, seamless mating with AEM X-Series wideband gauge wiring harnesses.

Benefits

1. Immediate Plug-and-Play Accuracy: Factory-calibrated design means you can install the sensor and start tuning immediately without performing complex manual calibrations.
2. Extended Operational Lifespan: Offers significantly longer service life and higher tolerance to thermal shock and oil/fuel contamination.
3. Quicker Closed-Loop ECU Adjustments: Rapid response times allow standalone ECUs and gauge controllers to make faster closed-loop fuel corrections, improving engine safety.
4. Reliable Tuning Across All Fuel Types: Eliminates sensor failure anxiety when running high-octane leaded race fuels or aggressive ethanol blends.
5. Engine Protection: Delivers pinpoint AFR and Lambda readings to prevent engine damage caused by lean fuel conditions under heavy boost or load.
