Product Details

The Walker Sensor Only line focuses on direct replacement airflow sensing without replacing the full housing assembly. Part number 245-1355 is engineered for accurate signal output and consistent fuel trim control on applications such as the Jaguar XJ, Jaguar XF, Jaguar XKR, and Land Rover Range Rover Sport. Walker designs these MAF sensors with OEM-quality components and verifies calibration through production testing and on-vehicle testing.

This part cross-references Allmakes LR012073 and Cardone Reman 74-50081 for the same application.
