Intended Use and Compatibility

The presented fuel injector for Mercedes W204 C63 is a factory component of the M156.985 gasoline engine's fuel system. Using an original injector nozzle ensures:

• correct fuel delivery across the full load range of the V8 AMG engine,
• stable engine operation at idle and high RPMs,
• maintenance of factory performance parameters and throttle response.

This component is dedicated to gasoline systems, which is crucial for proper spray pattern characteristics and resistance to operating conditions in high-power engines.

Technical Characteristics of the Injector Nozzle

The original nozzle from the Injector Nozzles category was designed by the vehicle manufacturer for precise interaction with the engine control system. Using the correct injector translates to:

• precise fuel spray formation in the combustion chamber,
• optimal mixture combustion at various temperatures and loads,
• reduced risk of knocking and localized overheating,
• maintaining correct exhaust emission values in line with factory specifications.

Selecting the correct injector nozzle is particularly important in high-specific-output engines, where the tolerance margin for fuel delivery errors is small.

Condition of the Part and Benefits of Using a Used Part

The fuel injector is offered as a used part, originating from an original Mercedes-Benz fuel system. This type of component allows for:

• reduced repair costs compared to a new OEM part,
• maintaining factory specifications by using the original design,
• easier integration with the existing fuel and electrical system.

For workshops specializing in the Mercedes brand and for private users, this is a solution that enables a technically sound repair without the need for aftermarket replacements with uncertain parameters.

Importance of Functional Injectors in a Gasoline Engine

In the M156.985 engine, properly functioning injectors are crucial for maintaining stable engine operation. Defective components can lead to:

• uneven engine running and power loss,
• increased fuel consumption and reduced acceleration,
• accelerated wear of mechanical components due to improper combustion.
