Purpose and Function of the Injector Holder

The injector holder bracket is responsible for mechanically pressing the injector into its seat in the cylinder head, maintaining it in the correct working position. In BMW E81, E87 LCI, E90, E91 series vehicles and MINI R55, this component is crucial for:

• stable injector guidance during engine operation, even under high fuel system pressures,
• maintaining a sealed connection between the injector and the combustion chamber,
• reducing vibrations and micro-movements that could lead to seat wear or injector damage.

A properly selected bracket is important both when replacing injectors and when servicing the cylinder head or injector seals.

Advantages of Using an Original BMW Holder

Choosing an original holder from the BMW group ensures a perfect fit for the specific cylinder head and injector design. In practice, this means:

• factory-level fitment with the cylinder head seat and injector body, without the need for modifications,
• maintaining the correct clamping force, in line with manufacturer specifications,
• compatibility with interchangeable part numbers specified in BMW service documentation.

This allows the part to be used as a service component for fuel system repairs in the mentioned BMW and MINI models, helping to maintain engine operating parameters close to factory levels.

Condition and Service Application

The offered holder is a used part from disassembly, allowing for economical repair while maintaining original manufacturing quality. This type of component is particularly useful in situations where:

• the existing bracket was damaged or deformed during injector removal,
• there are problems with maintaining a seal under the injector and comprehensive seat servicing is required,
• injectors are being replaced and it is recommended to simultaneously inspect and potentially replace mounting components.

A used, original holder helps maintain the geometry and parameters specified by the manufacturer, which is important for precise injector installation.

Technical Support and Part Selection

When selecting a holder, it is advisable to pay attention to compatibility with the specific engine version and to use the correct reference numbers from BMW catalogs. If in doubt, it may be helpful to compare the part with the one removed from the vehicle and consult a mechanic specializing in the brand.
