Although relatively small, this rubber mounting plays an important role in keeping the air injection pump securely supported while reducing the transmission of mechanical vibration into the surrounding mounting brackets and engine components.
The secondary air injection system is part of the vehicle's emissions-control equipment. It supplies additional air to the exhaust system to support the oxidation of unburned exhaust gases under the operating conditions specified by the original system design.
The air injection pump and its associated brackets are exposed to engine vibration, heat, mechanical movement and repeated temperature changes.
To minimise the effects of these operating conditions, Porsche incorporates rubber mounting elements into the pump support assembly.
Part number 93011316100 is specifically identified in Porsche parts diagrams as the rubber mounting used with the air injection pump bracket.
The rubber material provides a degree of flexibility between connected components, helping absorb vibration while maintaining the required mounting arrangement.
Over time, the original rubber mountings can become hardened, cracked, compressed or separated through age and repeated exposure to heat.
When a mounting deteriorates, the air injection pump assembly may no longer be supported as effectively. This can lead to increased vibration, rattling, unwanted movement and additional mechanical stress on surrounding components.
Replacing worn mountings with the correct Porsche component helps restore the original support and vibration-isolation arrangement.
This genuine replacement part is particularly useful during air injection pump servicing, engine restoration and emissions-system maintenance.
Symptoms Of Wear Or Failure:
Rubber components naturally deteriorate with age, temperature exposure and mechanical loading.
On older Porsche 911 Turbo models, the original mounting elements may have been in service for decades.
Several symptoms can indicate that the air injection pump rubber mounting requires replacement.
- Visible surface cracking.
- Deep splits through the rubber.
- Crumbling or deteriorating material.
- Sections of rubber separating from the mounting assembly.
- Loss of the original flexible structure.
- Increased vibration around the air injection pump.
- Buzzing noises during engine operation.
- Noticeable movement of the pump assembly.
- Vibration-related noise from surrounding components.
- Metallic rattling near the pump assembly.
- Knocking or tapping noises.
- Noise that changes with engine speed.
- Vibration from loose mounting hardware.
Why Replacement Matters:
Replacing a deteriorated air injection pump rubber mounting helps maintain the original stability and vibration isolation of the pump assembly.
Although the mounting is a relatively small component, failure can introduce unnecessary movement and mechanical stress.
- Restores Pump Support: Helps secure the air injection pump in its intended mounting position.
- Reduces Excessive Vibration: Re-establishes the original vibration-isolating function.
- Helps Eliminate Rattling: Can resolve vibration-related noise caused by defective mountings.
- Protects Supporting Brackets: Reduces unnecessary mechanical loading.
- Maintains Correct Alignment: Supports the original pump mounting geometry.
- Helps Protect Adjacent Components: Limits movement that could place stress on nearby parts.
- Supports Air Injection System Reliability: Maintains the integrity of the pump installation.
- Prevents Further Mounting Deterioration: Replaces cracked or compressed rubber before the mounting fails completely.
- Suitable for Porsche Restoration: Helps retain the vehicle's original equipment configuration.
- Genuine Porsche Replacement: Provides the manufacturer-specified part number for the applicable mounting assembly.

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.

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
