• OEM Part Number: MG4789
• Category: Intake Manifolds

Purpose and function in the intake system

The rubber intake manifold seal is responsible for maintaining a seal between the intake manifold and adjacent air supply system components. A correctly selected and installed seal:

• stabilizes airflow in the intake manifold,
• reduces pressure drops in the intake,
• minimizes the risk of unfiltered air entering the engine,
• supports even cylinder operation and correct mixture dosing.

Thanks to its flexible, rubber construction, the component effectively compensates for minor thermal and mechanical deformations, which is particularly important in engines that have been in operation.

Design characteristics

The rubber intake manifold seal has been designed as a component that works with the intake manifold in selected Mercedes models. The material used ensures:

• adequate flexibility across a wide range of operating temperatures,
• resistance to typical loads occurring in the engine compartment,
• stable adhesion to the manifold contact surface.

These properties help maintain the tightness of the intake system over a long period of use, while maintaining correct engine operating parameters.

Component condition and service application

The offered intake manifold seal comes from the secondary market, making it a cost-effective solution for maintenance repairs. It can be used as a replacement part during:

• intake manifold service,
• disassembly and reassembly of the intake system,
• diagnostics of leaks in the intake area.

Selecting the correct seal for a specific engine version is crucial for maintaining proper tightness, so it is worth verifying compatibility with your vehicle before installation.
