You have 30 days to request a return. All sale items are final sale.
These AEM LSU 4.2 sensors have a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller.
Warranty- Never requires free-air calibration when used with an AEM Controller and connector plug.
- Specifically designed for use with AEM Wideband UEGO controllers
- Includes sensor and weld-on stainless-steel tall manifold bung
- Accurate to 0.1 AFR
