The O-ring is engineered to withstand continual exposure to engine heat, intake vacuum, vibration and oil vapours without hardening, flattening or cracking. Precision-moulded to its 79mm x 6mm dimensions, it provides replacement fitment, making it ideal during air flow meter replacement, intake servicing or preventative maintenance.
What This Product Does:
- Creates an airtight seal around the air flow meter.
- Prevents unmetered air from entering the intake system.
- Ensures accurate airflow measurement by the engine management system.
- Helps maintain the correct air-to-fuel ratio.
- Supports smooth engine performance and throttle response.
- Contributes to optimum fuel economy and lower emissions.
- Forms an essential part of the engine air intake system.
Symptoms Of Wear Or Failure:
- Rough or unstable idle.
- Vacuum or intake air leaks.
- Illuminated engine management or check engine warning light.
- Lean mixture fault codes.
- Hesitation during acceleration.
- Reduced engine performance.
- Increased fuel consumption.
- Whistling or hissing noises from the intake system.
- Hard, flattened or cracked O-ring during inspection.
- Failed emissions or MOT inspection.
Why Replacement Matters:
- The air flow meter O-ring is continually exposed to engine heat, intake vacuum, oil vapours and repeated thermal cycling. Over time, the sealing material naturally hardens, compresses or deteriorates, reducing its ability to maintain an effective airtight seal.
- A leaking O-ring allows unmetered air to bypass the air flow meter, causing inaccurate airflow readings and upsetting the engine's carefully calibrated air-to-fuel ratio. This can lead to rough running, poor throttle response, increased fuel consumption, emissions faults and engine management warning lights. If left unresolved, prolonged intake leaks may place unnecessary strain on ignition and fuel system components.

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 data helps the ECU calculate the correct fuel quantity, supporting efficient combustion, stable idle, smooth acceleration, and reliable diesel engine operation.
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 diesel fuel delivery and engine management
• Helps maintain smooth idle, throttle response, and acceleration
• Suitable for intake system fault diagnosis or repair
• OE Match replacement for Porsche 3.0L Diesel engine 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 sensor may cause rough idle, hesitation, poor acceleration, increased fuel consumption, smoke, engine warning lights, incorrect air flow readings, or reduced performance. 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
• Excess smoke or poor diesel combustion symptoms are present
• 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 958 Cayenne and 95B Macan 3.0L Diesel models.

Porsche 958 Cayenne 4.2L DIESEL 2011-18
A mass airflow sensor is used to determine the mass of air entering an electronically fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to calculate and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor.

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
