The air filter’s primary function is to clean the incoming air before it enters the engine’s intake system. It traps dust, dirt, pollen, and other airborne contaminants, helping protect internal engine components and maintain optimal combustion efficiency. A clean air filter supports smooth throttle response, consistent power delivery, and helps prevent premature engine wear.

Over time, air filters can become clogged with exhaust soot, road dust, and debris - restricting airflow, reducing engine efficiency, and increasing fuel consumption. Regular replacement with an OE Match filter ensures the engine continues to receive clean, unrestricted air, supporting optimal performance, fuel economy, and long term engine health.

Replace the air filter as part of routine maintenance, especially if you notice:
Reduced engine responsiveness
 Higher fuel consumption
 Visible dirt or discoloration on the filter element
 After driving in dusty or harsh conditions.

The filter is designed to fit perfectly within the factory airbox, sealing correctly against the housing to prevent unfiltered air from entering the intake system. Using a Genuine Porsche air filter ensures the engine continues to operate exactly as Porsche intended, particularly important for high-output and motorsport-derived engines.

The engine air filter plays a critical role in protecting the engine while supporting optimal combustion. As air is drawn into the intake system, it carries dust, dirt, and microscopic debris that can cause internal engine wear if not filtered properly.

The air filter:
  Removes harmful airborne contaminants before they reach the engine
  Maintains correct airflow for efficient combustion
  Supports stable power delivery and throttle response
  Helps preserve long-term engine reliability and performance

By ensuring only clean, properly metered air reaches the combustion chambers, this filter protects vital engine components such as pistons, valves, cylinder walls, and sensors.

High-performance Porsche engines rely on precise airflow management. A clogged, incorrect, or poorly manufactured air filter can lead to restricted airflow, reduced efficiency, and increased internal wear. Using a Genuine Porsche air filter ensures:
  Factory-correct airflow and filtration balance
  Protection of sensitive internal engine components
  Maintained performance and throttle response
   Compliance with Porsche service and maintenance standards

Replace the air filter if:
  The filter element shows visible dirt or heavy discoloration
  Engine response feels reduced or inconsistent
  Fuel consumption has increased
  The vehicle has reached a scheduled service interval
  The car is driven frequently in dusty or high-pollution environments

Regular inspection and replacement help protect engine health and performance.

Replacement engine air filter produced to OE standards, meaning it closely replicates the original Porsche factory filter in dimensions, sealing surfaces, filter media, and airflow behaviour. It installs directly into the factory airbox with no modification required and provides dependable performance for routine maintenance or replacement.

The pleated filter media is engineered to trap dust, dirt, pollen, and fine airborne contaminants while maintaining the airflow needed for efficient combustion. OE Match quality ensures compatibility and performance comparable to the original part.

The engine air filter’s primary role is to clean incoming air before it enters the engine. Unfiltered air can carry abrasive particles that may cause premature wear to internal components such as pistons, valves, and cylinder walls. By capturing contaminants while allowing clean air to flow freely, the OE Match air filter helps:

  Protect internal engine components
  Maintain proper air-to-fuel ratios
  Support smooth throttle response and power delivery
  Preserve engine efficiency and reliability

Replacing a worn or clogged filter restores proper airflow and helps keep the engine operating close to factory parameters.

Air filters naturally become clogged over time as they trap contaminants. A restricted filter can reduce airflow, affecting engine efficiency and performance. Symptoms of a worn air filter may include:
  Reduced throttle response
  Increased fuel consumption
  Restricted intake airflow
  Increased engine wear from poor filtration

Installing a fresh OE Match air filter restores clean airflow and effective filtration, supporting continued engine protection and performance.

Replace the air filter if any of the following apply:
  Visible dirt, dust, or discoloration on the filter media
  Reduced engine responsiveness
  Higher fuel consumption
  Scheduled service interval reached
  Frequent driving in dusty or polluted environments

Regular inspection and timely replacement help maintain optimal engine health.

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.

How to Choose the Perfect Air Filter for Your Porsche #porsche #porscheupgrade

Today we’re talking air filters: the unsung heroes of your car’s engine. Why does your Porsche need one? Where can you find it? And, crucially, how do you know when it’s time for a replacement? It’s all here. We’ll unpack the options: classic paper filters (basic but effective); cotton gauze and foam alternatives (reusable & sustainable); and the pièce de résistance – air induction kits. The latter promises cooler, denser air for your engine: more oxygen, better combustion, and potentially, sharper performance.
