Why Replace This Part?
The air filter becomes dirty and restricted over time as it traps dust, road debris and airborne particles. A clogged or old filter can reduce airflow, affect engine performance, increase fuel consumption and allow poor filtration if the element is damaged. Replacing it with a Genuine Porsche OE air filter helps maintain proper airflow and protects the engine with the correct factory-specified filter element.
When to Replace This Part
• During routine service or maintenance
• If the air filter is dirty, clogged or oil-contaminated
• If engine performance or throttle response feels reduced
• If the engine has been used in dusty or dirty conditions
• If the filter element is damaged, crushed or deteriorated
• When recommissioning a stored classic Porsche 911
• When restoring the intake system with correct OE Porsche parts.
Where It Fits on the Car
This air filter fits in the engine air intake system, inside the air filter housing / air box. It filters incoming air before it reaches the intake and fuel injection system.

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.
