Product Details
Wideband UEGO Sensor with Stainless Tall Manifold Bung Install Kit by AEM Performance Electronics®. Bosch 4.2LSU Wideband UEGO sensor and stainless steel bung specially designed for use in individual port applications. Sensor is accurate to 0.1 AFR, laboratory calibrated at the factory, and never requires free air calibration. Finned, stand-off design of bung cools sensor body and minimizes restriction in exhaust port.

Ordinary “narrow band” O2 sensors, like those used on production vehicles, are only accurate within a very narrow AFR range, the region surrounding stoichiometric operation and leaner. In the rich region where high-performance engines usually operate, they are highly inaccurate. The Bosch 4.2LSU UEGO sensor however, is a wideband sensor and able to detect the exhaust’s O2 content across a wide range. It uses a “current pump” to determine the actual oxygen concentration within the sensing element. The output is in the form of a very small current, which varies depending on the air/fuel ratio. This is completely different from a narrow band O2 sensor, which directly outputs a voltage. The UEGO sensor design allows measurement of the exact AFR over the entire operating range.
Each AEM UEGO sensor is individually calibrated and a resistor integral at the connector body is laser trimmed with this value. This process replaces the traditional “free air” calibration procedure when changing sensors and implements a sensor specific calibration for unparalleled accuracy.
The stainless steel weld-in sensor bung is specifically designed so the sensor can provide accurate AFR readings with minimal flow intrusion and survive extreme exhaust gas temperatures.
