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

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

OEMatch Air Injection Pump / Air Injectors — Fit, Function, Confidence
OEMatch Air Injection Pump / Air Injectors provide replacements and related items for Porsche models. OEMatch focuses on air injection pumps and injectors selected for Porsche applications. These parts support emissions control at cold start and help the catalytic converter reach operating temperature more quickly, improving idle stability until normal running temperature is achieved.
Available Types
- Air injection pumps
- Air injectors
- Associated hoses, check valves and mounting hardware
Understanding OEMatch Air Injection Pump / Air Injectors
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air injection pumps and injectors.
OE (Original Equipment) refers to parts matching original specifications for the air injection pumps and injectors and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air injection pumps and injectors engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The secondary air injection system uses a pump and injectors to introduce fresh air into the exhaust stream during cold starts. This added air accelerates catalytic converter warm-up, encourages combustion of unburnt fuel, reduces hydrocarbon emissions and helps maintain a smooth idle while the engine reaches normal operating temperature.
Benefits Include
- Improved cold-start combustion and smoother idle
- More reliable emissions control during warm-up
- Reduced risk of catalytic converter overheating or contamination
Why Air Injection Pump / Air Injectors Wear and Fail
- Moisture ingress and internal corrosion of pump components
- Carbon and deposit build-up that blocks injector ports or valves
- Cracked or leaking hoses, valves or seals reducing airflow
- Electrical faults, relays or control issues affecting pump operation
The Importance of Replacing with OEMatch Air Injection Pump / Air Injectors
Replacing worn or faulty air injection pumps and injectors restores proper exhaust air delivery during cold start, helping the catalytic converter reach operating temperature promptly and reducing emissions. Timely replacement can improve drivability at idle, prevent downstream exhaust damage and support regulatory compliance for Porsche vehicles where emissions testing applies.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Components selected for compatibility with factory mounting points and clearances
- Options for pump, injector and associated hose or valve replacement without replacing unrelated assemblies
