This is a panel-type engine air filter element that fits directly into the air intake system of specified Porsche 911 (996/997) non-turbo cars. It is engineered to the same dimensions as the original Porsche part and constructed to the same quality standards, making it a reliable replacement for routine maintenance.
Fits:
Porsche 996 Carrera 2 / 4 / 4S 1998 - 2005
Porsche 997.1 Carrera 2 / 2S 2005 - 2008
Porsche 997.1 Carrera 4 / 4S 2005 - 2008

The air filter’s primary function is to clean the incoming air before it enters the engine’s intake system. It traps dust, dirt, pollen, and other airborne contaminants, helping protect internal engine components and maintain optimal combustion efficiency. A clean air filter supports smooth throttle response, consistent power delivery, and helps prevent premature engine wear.
Over time, air filters can become clogged with exhaust soot, road dust, and debris - restricting airflow, reducing engine efficiency, and increasing fuel consumption. Regular replacement with an OE Match filter ensures the engine continues to receive clean, unrestricted air, supporting optimal performance, fuel economy, and long term engine health.
Replace the air filter as part of routine maintenance, especially if you notice:
• Reduced engine responsiveness
• Higher fuel consumption
• Visible dirt or discoloration on the filter element
• After driving in dusty or harsh conditions.

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.

Understanding OEMatch Air Filters
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air filters.
OE (Original Equipment) refers to parts matching original specifications for the air filters and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air filters engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Air filters trap airborne particles, help keep air–fuel ratios stable and protect pistons, valves and cylinder walls from abrasive contamination. Choice of media and service interval depends on driving conditions, local environment and model-specific intake layouts; inspect the element at service intervals and replace when clogged or damaged.
OEMatch provides a wide selection of Porsche-compatible parts and has catalogued over 4,000 individual part numbers and over 8,700 OE cross-references to support maintenance and repairs. The product range is developed to help owners maintain, restore and use Porsche vehicles across multiple generations.
Benefits Include
- Protects engine internals from dust and abrasive particles
- Helps preserve fuel economy and consistent combustion
- Makes routine servicing straightforward with identifiable part references
Why Air Filters Wear and Fail
- Progressive clogging from dust, pollen and road debris
- Moisture or oil contamination that reduces filtration capacity
- Media degradation from age, heat exposure or mechanical damage
The Importance of Replacing with OEMatch Air Filters
Timely replacement preserves engine protection and consistent performance for Porsche models. Selecting the correct media and correct reference for your vehicle avoids fitment issues, reduces the risk of unfiltered air entering the intake and supports predictable service intervals.
Advantages
- Choice of media types to suit standard service, restoration or performance preferences
- Direct-fit replacements engineered to match original dimensions and tolerances
- Clear part references to assist correct selection for Porsche models
