Wideband UEGO Sensor wit h Stainless Tall Manifol

The Wideband UEGO Sensor with Stainless Tall Manifold (AEM 30-2063) is a precision oxygen measurement system designed for engine tuning enthusiasts, performance builders, and motorsport professionals who demand accurate air-fuel ratio monitoring. This replacement sensor integrates with wideband UEGO controllers to provide real-time oxygen data across a broad lambda range, enabling precise fuel mapping and engine optimization. Whether you're tuning a naturally aspirated engine, forced induction platform, or racing application, this sensor delivers the feedback necessary to maximize power output while maintaining reliability and fuel efficiency.

Based on proven Bosch LSU 4.5 sensor technology, the wideband UEGO design measures oxygen content across a wide combustion spectrum—from rich (12:1) to lean (20:1) air-fuel ratios—far exceeding the narrow range of conventional narrowband sensors. The stainless steel tall manifold construction provides durability in high-temperature exhaust environments while resisting corrosion and thermal stress. The sensor's advanced zirconia cell and pump cell design generate accurate voltage signals that feed directly into AEM 4-channel wideband controllers, allowing tuners to monitor and log precise AFR data for each cylinder bank or engine section in real time.

This sensor is ideal for anyone running engine management systems that require wideband feedback—turbo and supercharged platforms, naturally aspirated performance builds, and custom engine swaps all benefit from accurate AFR monitoring. Installation requires integration with a compatible wideband controller and proper exhaust port bossing; many users install one sensor per cylinder bank or intake manifold plenum for comprehensive air-fuel ratio data. Compact at 4.4 x 2.3 x 4.7 inches and weighing just 0.5 lbs, it fits tight engine bays while the stainless tall manifold design clears common exhaust configurations and turbocharger mounting points.
