The engine air filter’s primary role is to filter all air entering the engine before combustion. Air drawn into the intake carries microscopic debris from the environment - dust, pollen, sand, soot and other particulates. The genuine Porsche filter traps these contaminants while still allowing the engine to draw the clean, unrestricted air it needs for efficient combustion. By maintaining clean intake airflow, this filter supports:

•  Protection of internal components (valves, pistons, cylinder walls) from abrasive particles
•  Consistent combustion efficiency for smooth performance
•  Steady throttle response and power delivery
•  Preserved fuel economy and emissions behaviour

Using the genuine Porsche air filter helps ensure the engine continues to breathe precisely as Porsche designed it - balancing airflow and protection across all driving conditions.

Air filters protect the heart of the engine from harmful particles - but over time they accumulate dust and contaminants, reducing airflow and potentially influencing performance. A clogged or inefficient filter can result in:
•  Reduced throttle response
•  Higher fuel consumption
•  Restricted intake airflow
•  Increased wear on sensitive engine parts

Replacing the filter with a Genuine Porsche part restores optimal airflow and filtration, preserving performance, fuel economy, and engine longevity.

Consider replacing the air filter when:
•  Visible dust or dirt buildup is present on the media
•  Throttle response feels less responsive
•  Fuel economy has dropped
•  The vehicle has reached its scheduled maintenance service interval
•  The car is driven frequently in dusty or polluted environments.

Routine inspection and timely replacement help maintain overall engine health.

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.
