Ford Focus Mk3 ST Intake Manifold 2.0 Petrol EcoBoost DM5E-9424-CB

Ford Focus Mk3 ST Intake Manifold 2.0 Petrol EcoBoost is a component from the Intake manifolds category, designed to efficiently supply air to the petrol engine. A properly selected intake manifold stabilizes airflow, supports engine performance, and helps maintain the factory parameters of the fuel system. This model is intended for use in the sporty Focus ST variant with a 2.0 petrol engine.

Purpose and function in the intake system

The intake manifold in the version used in the Ford Focus Mk3 ST is responsible for evenly distributing air to all cylinders of the petrol engine. The correct geometry of the channels and the fitment to the 2.0 unit head ensure stable cylinder filling, which translates into predictable throttle response and repeatable performance. In the sporty ST variant, a properly functioning manifold is particularly important because it:

• maintains proper airflow across the entire rev range,
• supports the operation of the engine management system,
• reduces power drops resulting from leaks or disturbances in the intake.

Technical characteristics and fitment

The presented item belongs to the Intake manifolds category and was developed for a petrol unit, which means it is adapted to the specific combustion and operating parameters of a petrol-powered engine. The manifold design is compatible with the factory equipment of the Focus Mk3 ST, allowing it to be used as a replacement for the original equipment component. The product has dedicated manufacturer markings and interchangeable part numbers, which facilitates verification of compatibility with a specific vehicle configuration. Before purchasing, it is recommended to compare the markings with the vehicle data or consult a mechanic to confirm full compatibility with your specific engine version.

Condition, origin, and practical application

The offered manifold comes from dismantling and is marked as a used original part from Ford. This type of part is a good solution in situations where the factory manifold has suffered mechanical damage, deformation, or leaks causing engine performance issues. Using an original component from the secondary market allows you to maintain the factory airflow characteristics without the need for costly intake system modifications. In practice, such a manifold will work well both in standard operation and during more dynamic driving, typical for the ST version. It can be used as a replacement part during repairs, as well as when restoring the stock configuration after previous intake modifications.

Benefits of using an original intake manifold

Choosing an original intake manifold for the Focus Mk3 ST offers several significant advantages:

• Factory fitment – maintaining geometry and mounting points consistent with the manufacturer's design.
• Stable petrol engine operation – proper cylinder filling and predictable response to load.
• Consistency with the control system – no need to modify engine ECU maps resulting from changes in intake characteristics.
• The possibility of economical vehicle repair while retaining a component from the same design group as the factory-fitted part.
