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
