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.

The primary role of an engine air filter is to clean the air entering the engine’s intake system. As the engine draws in air for combustion, it also pulls in pollutants and particles from the environment. Without an effective filter, these contaminants can cause abrasive wear to pistons, valves, and other internal components.

By capturing and holding these particles, the air filter helps:
•  Protect internal engine components from abrasive contaminants
•  Maintain optimal air-to-fuel ratio for efficient combustion
•  Support consistent throttle response and performance
•  Help preserve fuel efficiency and engine longevity

Replacing a worn or clogged filter with an OE Match unit ensures that your Porsche continues to receive clean intake air just as it was designed to do.

Air filters collect contaminants over time. As the media becomes saturated with dust and debris, it restricts airflow and forces the engine to work harder to draw in the clean air it needs. A restricted filter can contribute to:
 Reduced engine responsiveness and power
 Higher fuel consumption
 Decreased combustion efficiency
 Potential internal wear from poorly filtered air

Installing a fresh air filter helps restore proper airflow and filtration efficiency, supporting continued smooth engine operation and protection.

Replace this air filter if any of the following apply:
  Visible dirt or discoloration on the filter media
  Reduced throttle response or sluggish acceleration
  Increased fuel consumption
  Scheduled maintenance interval reached
•  Frequent driving in dusty, polluted, or harsh environments.

Regular inspection and timely replacement help sustain engine performance and longevity.

The primary function of the Porsche 9P1129620 air filter is to clean incoming air before it enters the engine’s intake tract. It removes dust, pollen, dirt, and other airborne contaminants that could damage piston rings, cylinders, valves, or other delicate internal components if left unchecked. By ensuring only clean air reaches the engine, it supports stable combustion, efficient throttle response, and long-term engine health.

Using a Genuine Porsche air filter helps preserve the engineered balance between filtration efficiency and airflow, ensuring the engine receives the right amount of clean air required for proper combustion and performance.

Over time, air filters accumulate contaminants that restrict airflow and reduce engine efficiency. A clogged or worn air filter can lead to:
•  Reduced engine responsiveness
•  Increased fuel consumption
•  Greater intake restriction under load
•  Higher risk of internal wear from unfiltered debris.

Replacing the air filter with a Genuine Porsche part restores clean airflow, supports efficient combustion, and helps maintain factory-level engine performance and longevity.

Replace the air filter if:
•  The filter appears visibly dirty, dusty, or discoloured
•  Reduced throttle response or engine sluggishness is noticed
•  Scheduled maintenance interval is due
•  Driving frequently in dusty, off-road, or high-pollution environments.

Routine inspection and timely replacement help protect engine components and support peak performance.

The engine air filter’s primary role is to clean incoming air before it enters the engine’s combustion chambers. By trapping contaminants such as dust, pollen, and environmental debris, the air filter helps ensure the engine receives clean air needed for efficient combustion. This protects critical internal components like pistons, valves and cylinder walls from premature wear. Clean intake air also supports consistent power delivery, smooth throttle response and improved fuel economy.

Over time, air filters become loaded with trapped contaminants that restrict airflow and reduce combustion efficiency. A clogged or worn air filter can cause reduced throttle response, increased fuel consumption, and heightened engine wear due to unfiltered particles entering the intake. Replacing the air filter with a quality OE Match unit restores clean airflow, supports efficient engine function, and helps maintain performance and longevity.

Replace the air filter if you notice:
Visible dirt, dust build-up, or discoloration on the filter media
 Reduced engine responsiveness or power delivery
  Higher than normal fuel consumption
  After a specified service interval or frequent dusty driving.

HOW IS A BMC FILTER REGENERATED?

We recommend using original BMC kits only, as other products may not be effective or may damage the filter permanently, thus invalidating the warranty.

We recommend regenerating the filter (washing + oil application) every 20.000 – 25.000 km to ensure best performance and long service life.

This value is a rough estimate and can vary based on the climatic conditions and the ground on which the vehicle is used (sand, dirt roads, etc.).

The various steps to be carried out in order to regenerate the filtering element are indicated in the instructions contained in the regeneration kit.

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.
