This OE Match secondary air pump is an emissions control component designed for Porsche 958 Cayenne and 970 Panamera models equipped with the 4.8L V8 engine. The pump is part of the secondary air injection system, which helps reduce exhaust emissions during cold 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 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
