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.
