Walker 245-2254 Mass Air Flow Sensor
Walker Sensor Only Mass Air Flow Sensor 245-2254
Walker 245-2254 is a sensor-only mass air flow sensor for select Audi, Porsche, and Volkswagen applications. It is built as a standard replacement MAF sensor with a 5-terminal blade connector, oblong female plug, and flange mounting style for direct service on the listed vehicles.
Sensor Only Replacement Design
The Sensor Only line from Walker focuses on replacing the sensing element without the housing assembly. This approach is often chosen when the original housing is serviceable and the technician wants a faster, more economical repair path. Walker also programs and tests each sensor for fit, form, and function before release, with OE-quality components and calibrated flow characteristics.
