This is an electric air pump that forms the heart of the Porsche secondary air injection (SAI) system. In OE Match form, it’s manufactured to replicate the OE housing shape, mounting points, and electrical characteristics so it installs as a direct replacement when the original pump becomes noisy, weak, or fails.

On cold start, the pump pushes fresh air into the exhaust stream (via the SAI system valves and pipework). This helps the catalytic converters warm up faster and reduces cold-start emissions - supporting smooth compliance with the vehicle’s emissions strategy.

A failing secondary air pump can trigger emissions warnings and drivability annoyances (MIL/check engine light) because the ECU may detect insufficient secondary air flow during cold start. Replacing the pump restores proper SAI operation and helps keep emissions functions working as intended.

When to replace:
• Check engine light / emissions-related fault codes linked to secondary air flow
  Pump runs loudly, squeals, or sounds rough on cold start
  Pump not running during cold start when commanded
  Water ingress/corrosion damage or seized pump motor
  Preventative replacement during secondary air system service

Secondary air pump
This genuine Porsche Secondary Air Pump is an original factory emissions-control component designed for the Porsche 911 (997) Turbo models equipped with the 3.6 L twin-turbo engine. This pump forms part of the secondary air injection (SAI) system, which works with the engine management system and catalytic converters to reduce exhaust emissions during engine start-up.

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 injects fresh air into the exhaust system during cold engine start-up. This additional oxygen helps burn unburned hydrocarbons in the exhaust gases, allowing the catalytic converters to reach operating temperature more quickly and significantly reducing harmful emissions. The pump is automatically controlled by the vehicle’s engine control unit (ECU) and operates only during specific operating conditions, mainly during cold starts.

Functions & Technical Role Secondary air injection:
  Supplies fresh air to the exhaust system during cold start
  Emissions reduction: Helps oxidize unburned hydrocarbons in exhaust gases
  Catalytic converter warm-up: Accelerates catalyst operating temperature for cleaner emissions
  ECU-controlled operation: Works with sensors and air valves within the emissions system
  OEM reliability: Designed to meet Porsche’s airflow and durability specifications

Fitment / Position on Car
  Fitting position: Engine compartment / emissions system
  Location: Mounted within the secondary air injection system near the engine
  System: Exhaust emissions control / secondary air injection system

Secondary air pumps are exposed to heat, moisture, and frequent start-up cycles. Over time, internal electric motors or air channels may fail, which can cause:
  Check engine light related to the secondary air system
  Higher emissions during cold start Failed emissions testing
  Reduced catalytic converter efficiency

Replacing a faulty pump with a genuine Porsche OE component restores proper emissions system operation and ensures the vehicle continues to meet performance and environmental standards.

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

About Air Injection Pump / Air Injectors

Air Injection Pumps & Air Injectors – Clean Performance & Efficient Emissions for Porsche Engines

Air injection pumps and air injectors are essential components of Porsche’s secondary air injection system, designed to improve cold-start performance and reduce harmful exhaust emissions. By injecting fresh air into the exhaust manifold or catalytic converter, these parts help burn un-combusted fuel during startup, allowing the engine to warm up faster and operate more efficiently.

At Design911, we supply a comprehensive range of genuine and high-quality air injection pumps and air injectors for various Porsche modes including,  911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is engineered for precise airflow, quiet operation, and long-term durability — ensuring your Porsche remains compliant with emissions standards while maintaining peak performance.

What Do Air Injection Pumps & Air Injectors Do?

The secondary air injection system uses these components to introduce clean air into the exhaust stream to support combustion and emissions control. Specifically, they:

  • Inject fresh air into the exhaust system during cold starts.
  • Accelerate catalytic converter warm-up for cleaner operation.
  • Reduce unburned hydrocarbons and lower emission output.
  • Support smooth idle and efficient fuel burn during startup.

Together, the air injection pump and injectors help your Porsche meet performance and emissions regulations, particularly under strict testing conditions.

Why Do Air Injection Pumps & Air Injectors Fail?

These components are exposed to high temperatures, moisture, and contaminants, making them prone to wear and degradation over time. Common causes of failure include:

  • Moisture ingress leading to internal corrosion.
  • Carbon buildup clogging injector ports or valves.
  • Cracked or leaking hoses reducing airflow efficiency.
  • Electrical or relay faults affecting pump operation.
  • Contaminated air passages impairing airflow.

Symptoms of failure include rough cold starts, engine warning lights, failed emissions tests, unusual noises, or reduced performance at idle.

Why Replace Faulty Air Injection Components?

A malfunctioning air injection pump or injector can cause increased emissions, poor drivability, and potential damage to the catalytic converter. Replacing worn components restores optimal airflow, smooth operation, and regulatory compliance.

Benefits of replacement include:

  • Improved cold-start performance and smoother idle.
  • Reliable emissions control and efficiency.
  • Prevention of catalytic converter damage.
  • Long-lasting durability with manufacturer-quality precision.

All air injection components at Design911 feature high-quality materials, corrosion-resistant housings, and precision-engineered internal valves to ensure consistent airflow and long service life.
