This item is an authentic Porsche intake air filter element that installs in the factory airbox of select Porsche 981 models. Genuine Porsche parts are produced with Porsche-approved materials, manufacturing tolerances, and quality control processes - the same standards used when your car was new.

The engine air filter’s primary role is to clean all incoming air before it enters the engine’s combustion chambers. Incoming air naturally carries particles such as dust, pollen, and debris - which, if left unfiltered, can damage internal engine components and degrade performance over time.

By effectively filtering intake air while maintaining the correct airflow balance, the air filter helps:
• Protect internal engine components from abrasive contaminants
• Maintain proper air-to-fuel mixture for efficient combustion
• Support stable throttle response and performance
• Preserve fuel efficiency and engine longevity.

Using a genuine Porsche filter ensures your vehicle continues to benefit from the engineered balance between filtration efficiency and airflow performance that Porsche designed into the intake system.

Even the best-designed air filters gradually accumulate trapped contaminants, which can restrict airflow and reduce combustion efficiency. A clogged or degraded air filter can lead to:
•  Reduced engine responsiveness and power
•  Higher fuel consumption
•  Restricted intake airflow under load
•  Increased wear on internal engine parts.

Replacing the air filter with a Genuine Porsche part ensures proper filtration and airflow are maintained - matching the original design for long-term engine protection and performance.

Replace this air filter if any of the following apply:
•  Visible dirt, dust, or discoloration on the filter media
•  Reduced throttle response or sluggish acceleration
•  Noticeable increase in fuel consumption
•  Scheduled maintenance interval has been reached
•  Frequent driving in dusty, polluted, or harsh environments.

Regular inspection and timely replacement help sustain optimal engine health and performance.

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
