This AEM Bosch 4.2 LSU wideband UEGO sensor kit includes the laboratory‑calibrated LSU 4.2 sensor and a stainless steel tall manifold bung for weld‑in installation. Specifically made for use with AEM 4‑Channel Wideband controllers and boosted applications, the sensor is accurate to 0.1 AFR and, when used with an AEM controller, does not require free‑air calibration, simplifying installation and tuning on forced‑induction engines.
