Air Flow Meter O-Ring, 79 x 6. Porsche 957 / 958 Cayenne 2007-17  ❭  95511064610

Air Flow Meter O-Ring, 79 x 6.
The OE MATCH Air Flow Meter O-Ring, 79 x 6 is a sealing component designed to provide an airtight seal between the air flow meter and the adjoining intake system components on compatible Porsche models.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.

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.
