Replacement engine air filter produced to OE standards, meaning it closely replicates the original Porsche factory filter in dimensions, sealing surfaces, filter media, and airflow behaviour. It installs directly into the factory airbox with no modification required and provides dependable performance for routine maintenance or replacement.

The pleated filter media is engineered to trap dust, dirt, pollen, and fine airborne contaminants while maintaining the airflow needed for efficient combustion. OE Match quality ensures compatibility and performance comparable to the original part.

The engine air filter’s primary role is to clean incoming air before it enters the engine. Unfiltered air can carry abrasive particles that may cause premature wear to internal components such as pistons, valves, and cylinder walls. By capturing contaminants while allowing clean air to flow freely, the OE Match air filter helps:

•  Protect internal engine components
•  Maintain proper air-to-fuel ratios
•  Support smooth throttle response and power delivery
•  Preserve engine efficiency and reliability

Replacing a worn or clogged filter restores proper airflow and helps keep the engine operating close to factory parameters.

Air filters naturally become clogged over time as they trap contaminants. A restricted filter can reduce airflow, affecting engine efficiency and performance. Symptoms of a worn air filter may include:
•  Reduced throttle response
•  Increased fuel consumption
•  Restricted intake airflow
•  Increased engine wear from poor filtration

Installing a fresh OE Match air filter restores clean airflow and effective filtration, supporting continued engine protection and performance.

Replace the air filter if any of the following apply:
•  Visible dirt, dust, or discoloration on the filter media
•  Reduced engine responsiveness
•  Higher fuel consumption
•  Scheduled service interval reached
•  Frequent driving in dusty or polluted environments

Regular inspection and timely replacement help maintain optimal engine health.
