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

Engine air filters are wear-item components that become loaded with trapped contaminants over time. A clogged or heavily soiled air filter can restrict airflow, which may lead to:
•  Reduced engine responsiveness
•  Decreased fuel efficiency
•  Increased intake restriction and engine load
•  Premature wear of internal engine parts.

Replacing the air filter with a Genuine Porsche Part restores clean airflow and filtration efficiency, helping ensure long-term engine health and performance.

Replace the air filter if you observe any of the following:
•  Visible dust, dirt, or discoloration on the filter element
•  Reduced throttle response or sluggish acceleration
•  Higher than normal fuel consumption
•  Scheduled maintenance interval reached
•  Frequent driving in dusty, harsh, or polluted environments.

Routine inspection and timely replacement help maintain optimal engine protection and performance.
