Information
Secondary air pump
This OE Match secondary air pump is an emissions control component designed for Porsche 911 (997) Turbo models with the 3.6L engine. The pump forms part of the secondary air injection system, which introduces fresh air into the exhaust system during cold engine start-up to help reduce emissions.
Fits:
Porsche 997.1 Turbo 3.6L 2007 - 2009 (9770)
Porsche 997.2 Turbo 3.6L 2010 - 2012 (9770)
Diagram ref no 1
The secondary air pump is part of the air injection system used in many high-performance Porsche engines to control emissions during cold start conditions. When the engine is first started, the pump forces fresh air into the exhaust manifolds, allowing unburned fuel in the exhaust gases to oxidise and burn more completely.
This process allows the catalytic converters to reach their optimal operating temperature more quickly, reducing hydrocarbon emissions and helping the vehicle meet emissions regulations.
The OE Match pump is designed to match the original Porsche component in airflow capacity, electrical connections and mounting configuration, providing a reliable replacement during emissions system repair.
During cold engine start-up, the pump injects fresh air into the exhaust system. The additional oxygen promotes the combustion of residual fuel vapours in the exhaust gases, allowing the catalytic converters to heat up rapidly and operate efficiently.
Once the engine reaches normal operating temperature, the secondary air injection system typically switches off.
Function
• Secondary Air Injection: Delivers fresh air into the exhaust system during cold start
• Emission Reduction: Helps burn unburned hydrocarbons in exhaust gases
• Catalytic Converter Warm-Up: Speeds catalyst heating for improved efficiency
• ECU Integration: Operates as part of the vehicle’s emissions management system
Secondary air pumps operate during every cold start and are exposed to heat, moisture and vibration. Over time the internal motor or pump mechanism can fail, which may trigger a check engine light and increase emissions output. Replacing a faulty pump restores proper air injection and ensures the vehicle’s emissions system functions correctly.
When to Replace. Consider replacing the secondary air pump if you notice:
• Check engine light related to secondary air injection faults
• Increased cold-start emissions
• Unusual noise from the pump during startup
• Failure during emissions testing
