Air Mass/Flow Sensors
By OE Match
- Porsche Boxster 987 MKII 2.9L 2009-12
- Porsche Boxster S 987 MKII 3.4L 2009-12
- Porsche Cayman 2.9L 987C MKII 2009-12
- Porsche Cayman S / R 3.4L 987C MKII 2009-12
OE Match air mass / flow sensor for Porsche 987.2 Boxster and 987C.2 Cayman models. This replacement MAF sensor helps measure intake air flow, supporting correct fuel mixture, smooth running, reliable throttle response, and accurate engine management performance.
Fits:
Porsche 987.2 Boxster / Boxster S 2009 - 2012
Porsche 987C.2 Cayman / Cayman S 2009 - 2012
* A120 - 2.9L engines
* A121 - 3.4L engines
The air mass / flow sensor measures the amount of air entering the engine and sends this information to the engine control unit. Accurate air flow readings help the ECU calculate the correct fuel delivery, supporting efficient combustion, smooth idle, clean acceleration, and reliable performance.
Functions
• Replaces the air mass / flow sensor
• Measures intake air flow into the engine
• Sends air flow data to the engine control unit
• Supports correct fuel mixture and engine management
• Helps maintain smooth idle and throttle response
• Helps reduce hesitation, rough running, and poor acceleration
• OE Match replacement for Porsche 987.2 Boxster and 987C.2 Cayman intake system service.
Why Replace This Part?
Air mass / flow sensors can fail due to age, contamination, oil vapour, intake dirt, moisture, electrical faults, or damaged sensor elements. A faulty MAF sensor may cause rough idle, hesitation, poor acceleration, increased fuel consumption, engine warning lights, incorrect air flow readings, or poor running. Replacing the sensor helps restore accurate air measurement and reliable engine performance.
When to Replace This Part
• Engine warning light or MAF sensor fault code is present
• Idle is rough, unstable, or uneven
• Acceleration feels hesitant or flat
• Fuel consumption has increased
• Engine runs rich or lean
• Air flow readings are incorrect or intermittent
• Intake system service or diagnostic repair is being carried out.
Where it fits on the car
This sensor fits within the engine air intake system on Porsche 987.2 Boxster and 987C.2 Cayman models.

OEMatch Air Mass/Flow Sensors — Fit, Function, Confidence
Air mass and airflow sensors measure the volume and density of intake air and provide the engine control unit with data to set fuel delivery. OEMatch supplies replacement air mass/flow sensors for Porsche models, chosen for model compatibility to help restore accurate air measurement and reliable running.
Available Types
- Hot-wire mass air flow sensors
- Integrated air mass sensors with intake air temperature sensing
- Replacement modules compatible with common Porsche ECU connectors
Understanding OEMatch Air Mass/Flow Sensors
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air mass/flow sensors. OE (Original Equipment) refers to parts matching original specifications for the air mass/flow sensors and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air mass/flow sensors engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Air mass sensors detect incoming airflow and density and send this information to the ECU so it can calculate the correct air–fuel mixture; accurate measurement supports smooth running across load and temperature ranges.
Benefits Include
- Restored throttle response and smoother acceleration
- Improved fuel metering for more consistent running
- Reduced risk of drivability issues linked to incorrect air readings
Why Air Mass/Flow Sensors Wear and Fail
- Contamination from dirt, oil vapour or filter residue coating sensing elements
- Electrical faults, corrosion or damaged wiring and connectors
- Heat-related degradation of sensor electronics over time
- Air leaks downstream of the sensor causing incorrect readings
The Importance of Replacing with OEMatch Air Mass/Flow Sensors
Replacing a faulty air mass sensor restores accurate airflow measurement, which helps maintain proper fuel delivery and engine response. Timely replacement can prevent secondary faults and reduce the risk of prolonged poor running that may affect other engine systems. Select parts that match connector type and mounting to ensure straightforward fitting.
Advantages
- Direct-fit replacements made to original-spec dimensions and tolerances
- Electrical and connector compatibility for common Porsche models
- A practical supply option to support maintenance and repairs
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. If you are unsure about wiring or sensor calibration, seek professional installation.
