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 Porsche 958 Cayenne and 970 Panamera models equipped with the 4.8 L V8 engine. This pump forms part of the secondary air injection (SAI) system, which works alongside the catalytic converters and engine management system to reduce exhaust emissions during engine start-up.

Fits:
Porsche 958 Cayenne S / GTS / Turbo 4.8L 2011 - 2018
* option code: 7MG - Emissions concept EU 5
* option code: 7MJ - Emissions concept EU 5J
* option code: 7MM - EU6 plus exhaust concept

Porsche 970 Panamera S/ GTS / Turbo 4.8L 2010 - 2016
* option code: 165 - Emissions concept EU 5
* option code: 7MM - EU6 plus exhaust concept

The secondary air pump injects fresh air into the exhaust system during cold engine start-up. This additional oxygen allows unburned hydrocarbons in the exhaust gases to burn more completely, helping the catalytic converters reach their operating temperature faster and significantly reducing harmful emissions.

The pump operates automatically under the control of the engine management system and works together with secondary air valves and sensors to ensure proper emissions performance.

Functions & Technical Role
•  Secondary air injection: Pumps fresh air into the exhaust manifold during cold start
•  Emission reduction: Helps burn unburned fuel in exhaust gases
•  Catalyst warm-up: Speeds up catalytic converter activation for cleaner emissions
•  Engine management integration: Operates with ECU-controlled valves and sensors
•  OE reliability: Designed to match Porsche’s original airflow and electrical specifications

Fitment / Position on Car
•  Fitting position: Engine compartment / emissions system
•  Location: Mounted near the engine and connected to the secondary air injection system and exhaust manifold air passages
•  System: Exhaust emissions control system

Secondary air pumps operate during every cold start and are exposed to heat, moisture, and exhaust gases. Over time, internal components or the electric motor can wear out, potentially causing:
•  Check engine light related to the secondary air system
•  Increased cold-start emissions
•  Unusual noise during pump operation
•  Failure during emissions inspections

Replacing a worn pump with a genuine Porsche OE unit restores proper emissions control and ensures the engine management system operates as intended.

The secondary air pump is a critical component of the exhaust emissions control system. It injects fresh air into the exhaust manifold during cold starts, allowing unburned hydrocarbons in the exhaust gases to burn more completely. This process helps the catalytic converters reach operating temperature faster and reduces harmful emissions.

The OE Match pump is designed to match the factory Porsche unit in fitment, electrical connections and airflow characteristics. It integrates with the vehicle’s engine management system and secondary air valves to ensure proper emissions control performance.

Function
•  Secondary Air Injection: Pumps fresh air into the exhaust system during cold start
•  Emission Reduction: Helps burn unburned fuel in exhaust gases
•  Catalytic Converter Efficiency: Speeds up catalyst warm-up
•  Engine Management Integration: Works with the ECU and air injection valves

Secondary air pumps operate during every cold start and are exposed to moisture, heat and exhaust gases. Over time the pump motor or internal components may fail, which can trigger emission system faults or warning lights. Replacing a worn pump restores proper air injection and ensures the emissions system operates correctly.

When to Replace.  Consider replacing the secondary air pump if you notice:
•  Check engine light related to secondary air injection system
•  Increased cold-start emissions
•  Unusual noise from the pump during cold start
•  Failure during emissions inspection

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.
