Air Filters
Genuine Porsche Original Equipment (OE) engine air filter element — the factory-specified air intake filter designed for the Porsche 911 (997.2) Turbo and Turbo S (3.8 L) models. Fitted inside the vehicle’s airbox, it prevents dust, dirt, pollen, and airborne contaminants from entering the engine’s intake system while allowing unrestricted airflow.
Fits:
Porsche 997.2 Turbo 3.8L 2010 - 2013
Diagram ref no 2
The engine air filter element traps harmful particles from the incoming air stream, helping to ensure only clean, filtered air enters the engine’s combustion chambers. This protection helps maintain engine efficiency, performance, throttle response, and fuel economy, while also reducing wear on internal engine components.
Installed inside the airbox, this OE filter element forms a sealed barrier that prevents contaminants from bypassing the filter media. Its design supports proper airflow dynamics, reduces intake restriction, and keeps the engine’s air intake clean - especially important on high-boost turbocharged engines like the 3.8 L Turbo.
An air filter that is old, clogged, or damaged cannot effectively trap contaminants and may restrict intake airflow. This can lead to reduced engine performance, higher fuel consumption, and increased engine wear. Installing a new air filter ensures proper filtration and airflow performance as designed by the manufacturer, helping preserve engine power, efficiency, and long-term durability.
When to replace:
• Scheduled maintenance at service intervals
• After prolonged driving in dusty or dirty environments
• If filter media is visibly clogged, torn, or soiled
• During intake system servicing
• When restoring or recommissioning a 997 Turbo/Turbo S

OE Match replacement engine air filter element designed to match the original Porsche air cleaner cartridge used on 911 Turbo models. It fits within the factory airbox and filters incoming air before it reaches the engine intake system.
Fits:
Porsche 997.2 Turbo 3.8L 2010 - 2013
Diagram ref no 2
It removes contaminants from intake air, helping maintain clean airflow to the engine and supporting consistent running, throttle response, and long-term engine protection.
Function: Installed inside the factory air cleaner assembly, the filter forms a sealed barrier that allows high-volume airflow while trapping harmful particles. Replacing it at service intervals helps maintain proper intake efficiency and reduces strain caused by restricted airflow from a clogged element.
Over time, air filters load with dirt and debris, which can restrict airflow and reduce filtration efficiency. A fresh filter helps restore proper airflow, supports consistent performance, and protects the engine from abrasive particles that can accelerate wear.
When to replace:
• At scheduled service intervals
• Reduced performance or fuel efficiency linked to restricted airflow
• Filter appears dirty, clogged, or damaged
• After driving in dusty conditions
• During intake/airbox servicing

Includes special BMC detergent and an oil applicator - in either spray bottle or liquid form.

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.

This Product Fits:
Porsche 997 Turbo GT2 X51 / S 2009>>
Panel Filter Size:
- width - 245mm
- height - 150mm
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.
