Information
Replacement panel air filter
Designed for installation within the factory airbox, this OE Match filter integrates seamlessly with the original intake system and maintains the correct balance between filtration efficiency and unrestricted airflow. It is ideal for routine maintenance, servicing, or restoration work on Porsche 993 models.
Fits:
Porsche 993 1994 - 1997
The air filter cleans incoming air before it reaches the engine combustion chambers. By preventing contaminants from entering the intake system, it helps protect internal engine components, maintain performance, and support efficient combustion.
Function
• Filters dust, dirt, and airborne contaminants from intake air
• Maintains clean airflow into the engine
• Helps preserve engine performance and efficiency
• Protects internal engine components from wear
• Supports smooth combustion and throttle response
Over time, air filters become clogged with dirt and debris, restricting airflow to the engine. A dirty filter can reduce performance, throttle response, and fuel efficiency while increasing engine wear. Replacing the filter at regular service intervals helps maintain optimal airflow, engine protection, and reliable operation.
When to replace
• During routine scheduled servicing
• Reduced engine performance or throttle response
• Dirty or clogged filter element
• Increased fuel consumption
• After driving in dusty or harsh environments

Information
Replacement Air filter.
OE Match quality engine air filter designed as a direct replacement for the original intake air filter fitted to selected Porsche 911 (996 and 997) performance models. Manufactured to closely match original equipment specifications, it delivers correct fitment, reliable filtration efficiency, and proper airflow characteristics for consistent engine performance.
Fits:
Porsche 996 Turbo 2000 - 2005
Porsche 996 GT3 1999 - 2005
Porsche 996 GT2 2000 - 2005
Porsche 997.1 GT3 2007 - 2009
Porsche 997.2 GT3 2010 - 2011 (Not for RS)
Diagram ref no 2
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.

Information
Replacement panel air filter.
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.
