Aluminium Alloy Oil Separator Kit for 2018-2020 Ford Expedition Models

This oil separator is a direct-fit component designed exclusively for the 2018-2020 model years of the Ford Expedition full-size SUV. Supplied as a complete kit, it is ready for installation aimed at managing crankcase ventilation. The unit is fabricated from aluminium alloy, a material selected for its favourable strength-to-weight ratio and inherent resistance to corrosion, which is a practical consideration for components housed in the engine bay. Buyers can select from four distinct colour finishes—black, blue, red, or silver—offering a degree of customisation to match or accent the vehicle's existing engine compartment appearance. Its primary function is to separate oil vapour from the crankcase ventilation gases before they are recirculated into the engine's intake system.

Features and Construction

This product is defined by its specific application and material construction, offering a targeted solution for Ford Expedition owners.

Material and Build

The oil separator is constructed entirely from aluminium alloy. This choice of material contributes a lightweight structure to the assembly, which is a common benefit for aftermarket engine components where minimising added mass is often desirable. Aluminium alloy also possesses a natural resistance to corrosion, a relevant trait for a part exposed to engine heat, moisture, and various fluids. The construction focuses on providing the core separation function within a durable metallic housing.

Size and Practical Fit

The key specification for this product is its vehicle application range: it is designed for the 2018, 2019, and 2020 model years of the Ford Expedition. This precise fitment information is crucial for purchasers to confirm compatibility with their specific vehicle. The product is supplied as a complete set, containing all primary components necessary for a standard installation. This approach simplifies the procurement process, as the essential parts are included in one package.

Uses and Placement

Installed within the engine bay, this component serves a specific mechanical role and offers aesthetic customisation.

Event or Professional Use

For owners who use their Ford Expedition for towing, carrying heavy loads, or in performance-oriented driving scenarios, managing engine blow-by can be a consideration. An oil separator can help reduce the amount of oil vapour entering the intake tract under such conditions. The availability of different colours (black, blue, red, silver) also allows for a coordinated appearance in show vehicles or professionally maintained engine bays where visual presentation is a factor.

Everyday Home Use

For the typical Ford Expedition owner, this oil separator serves as a preventative maintenance component. By intercepting oil vapours, it can help minimise oil residue buildup in the intake system, intercooler (if applicable), and related hoses. This may contribute to maintaining intended engine performance and air intake cleanliness over extended periods and mileage. The choice of colour allows for a subtle or bold customisation touch under the bonnet according to personal taste.

Benefits and Buying Value

The value of this product lies in its targeted fitment, material choice, and the completeness of the kit provided.

Reuse and Low Maintenance

As a permanently installed mechanical component made from aluminium alloy, the oil separator is designed for long-term use. Depending on design, such units often feature serviceable internals that can be cleaned periodically. The corrosion resistance of the aluminium housing supports longevity in the harsh engine environment, suggesting a component intended to last for the duration of its service life with minimal material degradation.

Why Choose This Product

This product offers a clear, vehicle-specific solution for 2018-2020 Ford Expedition owners seeking an oil separation function. The assurance of correct fitment for these model years is a primary advantage over universal kits that require adaptation. The provision of a complete set reduces the need to source additional fittings or brackets separately. The aluminium alloy construction provides a balance of durability and weight, while the four colour options deliver a level of personalisation not always available with purely functional engine components.
