Cleaning Instructions:

Our filter uses a specially designed media that restores performance and efficiency to near new each time by simply cleaning it with compressed air (30-40 psi) from the inside out. Frequent washing is unnecessary in order to restore filter performance. For a deep cleaning after exposure to extreme environments, a biodegradable cleaner such as Simple Green or other mild shop degreaser can be used. Place the filter in a solution or spray the cleaner on the filter. Allow the solution to loosen dirt particulates and rinse thoroughly. Shake the filter or use compressed air from the inside blowing outward to remove residual water. Allow a full day to dry.

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

Engine Tuning Performance Air Filters – Maximise Airflow and Power for Your Porsche

A performance air filter is one of the most effective and accessible upgrades for improving your Porsche’s engine performance and responsiveness. Designed to increase airflow while providing superior filtration, these filters enhance combustion efficiency, throttle response, and horsepower output — making them essential for both road and track enthusiasts.

At Design911, we offer a premium selection of high-performance air filters and engine tuning intake upgrades for Porsche models. Manufactured using advanced filtration media and precision-engineered housings, these filters deliver improved airflow without compromising protection. Whether you’re upgrading a 911 Turbo, Cayman GT4, or Boxster, our manufacturer-quality performance air filters ensure long-lasting performance and reliability.

What Do Performance Air Filters Do?

Performance air filters allow your Porsche’s engine to breathe more efficiently by reducing airflow restriction and enhancing fuel-air mixture quality.

Core Functions:

  • Increase airflow to the engine for better combustion and power.
  • Filter harmful particles such as dust, dirt, and debris to protect the engine.
  • Improve throttle response and engine smoothness.
  • Enhance engine sound and performance feel.
  • Support long-term engine health by maintaining clean airflow.

By optimising the air intake system, a performance air filter helps your Porsche deliver sharper acceleration, greater efficiency, and improved drivability.

Why Do Air Filters Fail or Degrade?

Air filters operate in a harsh environment, exposed to debris, oil vapour, and temperature extremes. Over time, they can become clogged or damaged, restricting airflow and reducing performance.

Common Causes of Failure Include:

  • Clogging from dirt, dust, or pollen build-up.
  • Oil contamination (especially in reusable filters).
  • Physical damage to the filter material or seals.
  • Improper cleaning or maintenance.
  • Extended service intervals causing reduced airflow.

Symptoms of a failing air filter include reduced engine power, poor fuel economy, hesitation under acceleration, or unusual intake noise. Replacing or upgrading ensures consistent performance and protection.

Why Replace with a High-Performance Air Filter?

Upgrading to a precision-engineered performance air filter restores and enhances your Porsche’s breathing efficiency. These filters are designed to provide a perfect balance between airflow and filtration, delivering measurable performance gains.

Key Benefits:

  • Increases horsepower and torque output.
  • Improves throttle response and fuel efficiency.
  • Provides superior filtration for engine longevity.
  • Constructed from durable, reusable materials.
  • Direct-fit compatibility for Porsche 911, Cayman, Boxster, Panamera and more.
  • Ideal for performance tuning, track driving, or spirited road use.

Replacing restrictive stock filters with high-performance alternatives enhances both performance and reliability — essential for enthusiasts who demand the best from their Porsche.

Highlights:

  • High-performance air filters for Porsche tuning and upgrades.
  • Improved airflow, filtration, and power delivery.
  • Reusable and washable filter options available.
  • Engineered for precision fit and durability.
  • Perfect for classic and modern Porsche performance models.
  • Supports both performance gains and long-term engine protection.
