The air mass / flow sensor measures the amount of air entering the engine intake system. This information is sent to the engine control unit, allowing it to adjust fuelling, ignition, boost control, and overall engine performance.

Functions
• Replaces the air mass / flow sensor
•  Measures incoming intake air flow
•  Sends air flow data to the engine control unit
•  Helps support correct fuel mixture and engine performance
•  Assists with smooth idle, throttle response, and emissions control
•  Fits left and right side applications where specified
•  OE Match replacement for Porsche intake and engine management repair.

Why Replace This Part?
Air mass / flow sensors can fail due to age, contamination, oil vapour, air filter debris, moisture, electrical faults, or damaged intake components. A faulty sensor may cause poor idle, hesitation, reduced power, increased fuel consumption, engine warning lights, rough running, or incorrect boost and fuelling behaviour. Replacing the sensor helps restore accurate air measurement and reliable engine performance.

When to Replace This Part
•  Engine warning light or air flow sensor fault codes are present
•  Idle is rough, unstable, or uneven
•  Throttle response is poor or delayed
•  Engine power is reduced
•  Fuel consumption has increased
•  Hesitation, flat spots, or poor acceleration are present
•  Intake system or engine management faults are being diagnosed.

Where it fits on the car
This sensor fits in the engine intake air system. It can be used on the left or right side where applicable, depending on model and intake layout.
