Product Details

Walker Products has supplied fuel system and engine sensor components since 1946, with manufacturing and engineering support focused on meeting or exceeding OEM specifications. The Walker Mass Air Flow Sensor 245-2141 is part of that product line and is intended for accurate airflow measurement in vehicles that rely on precise sensor input for fuel and drivability control. This part is compatible with 1992-1995 BMW 325i, 1992-1995 BMW 325is, 1993-1995 BMW 525i, 1994-1995 BMW 530i, 1995 BMW M3, and 1993 BMW 525iT.

What It Helps Address

  • Rough idle caused by incorrect airflow signal output
  • Hesitation or stumble during acceleration
  • Lean or rich fuel mixture concerns tied to sensor drift
  • Check engine light conditions related to mass air flow sensor performance
  • Poor throttle response on BMW 325i, 525i, 530i, M3, and 525iT applications

Installation Notes

Verify connector style, terminal count, and housing requirements before installation. This sensor uses a female connector and does not include a housing, so the existing intake assembly must match the application. Confirm fitment by year, model, and engine management configuration for your BMW 325i, 325is, 525i, 530i, M3, or 525iT before replacement.

Quality Assurance

Walker Products is an ISO 9001/IATF16949 certified manufacturer with in-house product management and engineering support. The brand states its engine sensors are produced to meet or exceed OEM standards and specifications.
