Air Mass/Flow Sensors. Porsche 911 / 964  ❭  930606123X

This OE Match air mass / flow sensor is a replacement intake air measurement sensor for Porsche 911 and 964 models. This air mass / flow sensor fits in the engine intake system, positioned where it can measure incoming air before it reaches the throttle body / intake manifold. It connects to the vehicle’s engine management wiring and intake ducting according to the factory layout.

Fits:
Porsche 911 3.2L 1984 - 1989
Porsche 964 1990 - 1994

Diagram ref no 1

The air mass / flow sensor measures the volume or flow of air entering the engine intake system. This information is used by the engine control system to calculate the correct fuel delivery, helping maintain smooth running, throttle response, fuel economy, and emissions performance.

Functions
• Measures incoming intake air flow
• Sends air flow information to the engine management system
• Supports correct fuel mixture calculation
• Helps maintain smooth idle and throttle response
• Supports reliable engine performance and drivability
• Replaces faulty, worn, contaminated, or failed original air flow sensors
• OE Match replacement for intake and fuel injection system repair.

Why Replace This Part?
Air mass / flow sensors can fail or become inaccurate due to age, contamination, electrical faults, worn internal components, intake leaks, or long-term use. A faulty sensor may cause rough idle, hesitation, poor throttle response, flat spots, increased fuel consumption, emissions faults, difficult starting, or poor running. Replacing the sensor helps restore accurate intake air measurement and correct engine management operation.

When to Replace This Part
•  The engine has rough idle, hesitation, or poor throttle response
•  Air flow sensor fault codes or mixture faults are present
•  Fuel consumption has increased noticeably
•  The engine runs too rich or too lean
•  Starting or warm-running issues are present
•  The sensor is contaminated, damaged, or electrically faulty
•  The intake or fuel injection system is being serviced or repaired
