Product Details

The Walker Sensor Only line focuses on replacing the sensing element without changing the full housing assembly when the original housing is serviceable. For many repairs, that approach reduces labor and cost while still restoring accurate airflow measurement. Walker engineers calibrate these sensors for the vehicle’s airflow profile, and each unit is production tested and verified with on-vehicle validation before sale. Walker 245-2282 is a practical replacement for Audi vehicles where precise air metering is needed to maintain drivability and fuel control.

This part cross-references no listed aftermarket part numbers for the same application.

Installation Notes

Before installation, inspect the air intake tract, connector, and housing for dirt, oil residue, or damage. Handle the sensing element carefully to avoid contamination, and confirm the connector style matches the vehicle harness. On applications where the original housing is worn or contaminated, replacing the complete assembly may be the better service choice.
