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.

The cabin air filter cleans the air entering the passenger compartment, improving interior air quality and comfort for occupants. It also helps protect the HVAC system from contamination, supporting consistent airflow and efficient heating and cooling operation.

Function: Positioned in the HVAC intake path, the filter traps fine particles while allowing unrestricted airflow into the cabin. Genuine Porsche filtration media and sealing design ensure that unfiltered air cannot bypass the filter, maintaining optimal system efficiency and interior air cleanliness.

Over time, cabin air filters become saturated with dust, pollen, and pollutants, which can reduce airflow, degrade air quality, and place additional strain on the HVAC system. Replacing the filter with a Genuine Porsche OE component restores factory airflow levels, improves cabin comfort, and helps maintain long-term HVAC performance and reliability.

When to replace:
•  At recommended Porsche service intervals
•  Reduced airflow from vents
•  Persistent odours or poor cabin air quality
•  After extended driving in dusty or urban environments
•  During routine HVAC servicing

The cabin air filter screens incoming air before it enters the vehicle’s cabin ventilation system, capturing pollutants, pollen, dust, and debris that can reduce air quality and affect HVAC performance. A properly functioning filter helps maintain a clean and comfortable cabin environment, reduces HVAC system strain, and supports interior air quality - particularly beneficial for allergy sufferers and those driving frequently in urban or dusty environments.

Function: Installed in the HVAC intake, this OE Match filter traps fine particles while allowing airflow into the heating and air-conditioning system. Over time, cabin air filters can become clogged or saturated, which may reduce airflow and increase strain on the blower motor. This OE Match replacement restores proper filtration and airflow, helping the climate control system operate efficiently.

Over time, the cabin air filter accumulates dust, pollen, soot, and other airborne contaminants, which can restrict airflow, reduce HVAC efficiency, and degrade interior air quality. A clogged filter can force the HVAC system to work harder, increasing wear on the blower motor and reducing comfort levels. Installing a fresh OE Match filter helps maintain airflow, improve cabin air quality, and support efficient heating and cooling performance.

When to replace:
  After 12,000–15,000 miles or at regular service intervals
  If reduced airflow or unpleasant odours are noticed
  Following long exposure to dusty, polluted, or pollen-rich conditions
  When HVAC system is serviced for performance or maintenance

About Air Filters

Porsche Air Filters | Design911 Performance & Replacement Filters for Clean Engine Breathing

Air filters are essential for your Porsche’s performance, efficiency, and longevity. Designed to remove dust, pollen, and debris from incoming air, they ensure clean airflow to the engine for optimal combustion. A high-quality air filter not only improves power delivery and throttle response but also helps protect internal engine components from premature wear and damage.

At Design911, we supply a full range of air filters for both classic and modern models — including high-performance cotton gauze, pleated paper, and foam filters. Each filter is designed for precision fitment and maximum filtration efficiency. Whether you’re maintaining your daily driver or upgrading your Porsche for motorsport use, our filters deliver clean airflow, long service life, and reliable performance.

What Do Air Filters Do?

Air filters are a vital component of your Porsche’s intake system, providing clean, filtered air for efficient combustion and engine protection.

Core Functions:
• Filter out dust, dirt, and airborne contaminants from intake air.
• Maintain stable air-fuel ratios for smooth combustion.
• Protect pistons, valves, and cylinder walls from abrasive particles.
• Enhance throttle response and engine performance.
• Support optimal fuel economy and reduced emissions.

A well-maintained air filter ensures that your Porsche engine breathes efficiently — delivering consistent performance and reliability.

Why Do Air Filters Fail or Degrade?

Over time, air filters naturally clog with dirt and debris, reducing their ability to allow clean air into the engine.

Common Causes of Failure Include:
• Blockage from dust, pollen, and road debris buildup.
• Moisture or oil contamination in humid or dusty environments.
• Deterioration of filter media from age or heat exposure.
• Restricted airflow reducing performance and efficiency.
• Damage to seals allowing unfiltered air into the intake system.

A dirty or failing air filter can cause poor fuel economy, reduced power, increased emissions, and potential engine wear — making timely replacement essential.

Why Replace or Upgrade Your Porsche Air Filter?

Regular replacement or upgrading to a performance air filter ensures your Porsche continues to perform at its best, with clean, efficient airflow and maximum engine protection.

Key Benefits:
• Restores engine performance and responsiveness.
• Improves fuel efficiency and throttle sensitivity.
• Protects vital engine components from dust and contaminants.

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.
