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.
