Air Mass/Flow Sensors
The Genuine Porsche Air Flow Meter O-Ring, 79 x 6 is an original equipment sealing component designed to provide an airtight seal between the air flow meter and the adjoining intake system components on compatible Porsche models. Manufactured to Porsche's exact specifications for fit, sealing performance and durability, this precision-moulded O-ring prevents unmetered air from entering the intake system, ensuring the engine management system receives accurate airflow readings for optimum performance, fuel efficiency and emissions control.
Sold Each.
Fits:
- Porsche 957 Cayenne S / GTS 4.8L 2007-10
- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
- Porsche 958 Cayenne S V8 4.2L Diesel (382Hp) 2010-17
Diagram Ref No 13
Manufactured from high-quality fuel-, oil- and heat-resistant elastomer, 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 direct 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.
- Restores factory intake sealing performance.
- 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.
- Replacing the original seal with a Genuine Porsche Air Flow Meter O-Ring restores the integrity of the intake system and ensures accurate airflow measurement. Manufactured to Porsche's exact engineering standards using premium-quality sealing materials, it provides factory-correct fitment, exceptional durability and long-lasting sealing performance, helping maintain the efficiency, reliability and performance expected from your Porsche.

Porsche 957 Cayenne V8 4.8L S / GTS MKII
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.

Air Mass Sensors – Precision Airflow Measurement for Porsche Performance
Air mass sensors (also known as mass air flow sensors or MAF sensors) are critical components in your Porsche’s engine management system. They measure the exact volume and density of air entering the engine, allowing the ECU to calculate the correct air-fuel mixture for efficient combustion, performance, and emissions control.
At Design911, we offer a comprehensive range of genuine and high-quality air mass sensors for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each sensor is designed for precision accuracy, responsive measurement, and long-term reliability — ensuring smooth power delivery, optimal fuel economy, and consistent engine performance.
What Do Air Mass Sensors Do?
The air mass sensor monitors the flow of
incoming air to the engine and sends data to the vehicle’s ECU (Engine Control
Unit). Its main functions include:
- Measuring air intake to calculate the optimal air-fuel ratio.
- Ensuring efficient combustion for performance and emissions compliance.
- Supporting fuel economy by adjusting fuel delivery based on driving conditions.
- Maintaining smooth engine operation under all loads and temperatures.
A properly functioning MAF sensor ensures your
Porsche delivers the responsiveness, efficiency, and precision it was
engineered for.
Why Do Air
Mass Sensors Fail?
Air mass sensors are delicate electronic
components and can degrade over time due to contamination, wear, or electrical
issues. Common causes of failure include:
- Contamination from dirt, oil vapour, or air filter residue coating the sensor wire.
- Electrical faults or corrosion in the wiring harness or connectors.
- Sensor burnout due to prolonged high temperatures.
- Air leaks downstream of the sensor causing incorrect readings.
- Use of low-quality air filters or poor servicing introducing debris into the intake.
Symptoms of a failing air mass sensor include rough idling, reduced power, poor acceleration, increased fuel consumption, or an illuminated engine warning light.
Why Replace a Faulty Air Mass Sensor?
A faulty or inaccurate MAF sensor can severely impact your Porsche’s performance, leading to poor drivability, high fuel use, and potential damage to other engine components. Replacing it restores proper airflow measurement and engine efficiency.
Benefits of replacement include:
- Restored throttle response and smooth power delivery.
- Optimised fuel economy and emissions control.
- Prevention of stalling, hesitation, or misfires.
- Reliable, manufacturer-quality sensor performance and lifespan.
All air mass sensors supplied are made to meet or exceed exacting engineering standards, using advanced materials and sensor technology for precision airflow measurement and long-lasting durability.
