The engine air filter’s primary job is to clean intake air before it enters the engine’s combustion chambers. Proper filtration helps prevent abrasive particles from damaging internal engine components like valves, pistons, and cylinder walls. By capturing contaminants and helping maintain smooth airflow, this OE Match air filter supports:
• Protective filtration: Removes dust and debris from incoming air
• Optimised airflow: Allows clean air to reach the engine for efficient combustion
• Stable performance: Helps maintain throttle response and power delivery
• Engine longevity: Reduces wear caused by contaminants entering the intake.
A clean air filter is crucial for preserving engine health and maintaining consistent performance throughout everyday driving and spirited use.
Engine air filters are considered routine wear items that gradually become loaded with trapped debris. A dirty or clogged filter can restrict airflow, leading to:
• Reduced engine responsiveness
• Higher fuel consumption
• Increased intake restriction
• Premature wear on internal engine components.
Installing a fresh OE Match air filter restores proper airflow and filtration, helping keep your engine breathing clean air and running efficiently.
Replace this air filter if any of the following apply:
• Visible dust, dirt, or discoloration on the filter media
• Reduced throttle response or sluggish acceleration
• Higher than expected fuel consumption
• Scheduled maintenance interval reached
• Frequent driving in dusty, polluted, or harsh environments.
Routine inspection and timely replacement help sustain optimal engine health and performance.

Why Replace This Part?
The air filter becomes dirty and restricted over time as it traps dust, road debris and airborne particles. A clogged or old filter can reduce airflow, affect engine performance, increase fuel consumption and allow poor filtration if the element is damaged. Replacing it with a Genuine Porsche OE air filter helps maintain proper airflow and protects the engine with the correct factory-specified filter element.
When to Replace This Part
• During routine service or maintenance
• If the air filter is dirty, clogged or oil-contaminated
• If engine performance or throttle response feels reduced
• If the engine has been used in dusty or dirty conditions
• If the filter element is damaged, crushed or deteriorated
• When recommissioning a stored classic Porsche 911
• When restoring the intake system with correct OE Porsche parts.
Where It Fits on the Car
This air filter fits in the engine air intake system, inside the air filter housing / air box. It filters incoming air before it reaches the intake and fuel injection system.

BMC Air Filter.
This Product Fits:
Porsche 911 1966-76
Porsche 914 1970-76
Cylindrical Filter Size:
- width - 140mm
- height - 220mm
- diameter - 90mm
BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
DESIGN AND MATERIALS
Qualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.

Pop off air valve.
Fits:
Porsche 911 1973-89
Prevents costly airbox explosions, installed with the engine and air box in place. 911 engines since 1973 have had the bad habit of backfiring and blowing a hole an the air box. 911 POP VALVE is installed inside the air box and when a backfire occurs the valve will instantly open and release the backfire pressure. The POP VALVE then automatically closes and the angine continues to run. The POP VALVE has no effect on the performance or fuel mileage.
