Rejuvenate your existing BMC air filter using this kit.

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.

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.
• Available in reusable, high-performance, or replacement-grade options.
• Compatible with Porsche 911, 944, 968, Boxster, Cayman, Panamera, and Macan models.
• Ideal for regular maintenance, performance upgrades, or restoration projects.

Design911’s Porsche air filters combine engineering precision and superior materials for maximum performance, protection, and reliability on every drive.

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.
