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

This oil separator is an aftermarket engine component designed for 2018-2020 Ford Expedition SUVs. Its primary role is within the crankcase ventilation system, where it helps to separate oil mist from the blow-by gases before they are recirculated back into the engine's intake. This process can aid in maintaining cleaner intake tracts and reducing carbon deposits over time. The unit is constructed from aluminium alloy, a material chosen for its combination of light weight, machinability, and durability in the under-bonnet environment. The kit comes complete and is available in a choice of four distinct colour finishes: black, red, blue, and silver, allowing for a degree of aesthetic personalisation to match other engine bay modifications.

Features and Construction

This product is defined by its specific application, material choice, and available customisation. It is not a universal fit part but is engineered for compatibility with a defined range of vehicle model years. The construction and finish options provide its main practical differentiators.

Material and Build

The oil separator is fabricated from aluminium alloy. This material offers a favourable strength-to-weight ratio and is resistant to corrosion, which is beneficial for components located in the engine bay where they may be exposed to heat, vibration, and various fluids. The use of aluminium also facilitates precise machining for the internal baffles or media required for effective oil separation. The finish—whether black, red, blue, or silver—is typically achieved through anodising, a process that enhances the aluminium's surface hardness and provides the coloured layer.

Size and Practical Fit

The source information confirms the product is specifically applicable to Ford Expedition models from the 2018 to 2020 model years. This precise compatibility is crucial for correct installation and function, as mounting points, hose diameters, and engine bay clearances can vary between vehicle generations and models. Prospective buyers should confirm their vehicle's exact model year before purchasing. While specific dimensional measurements for the unit itself are not provided, it is supplied as a complete kit containing all necessary parts for installation as a single set.

Uses and Placement

The oil separator performs a specific mechanical function within the vehicle's engine system. Its use is tied directly to the operation and maintenance of the crankcase ventilation system on the applicable Ford Expedition.

Event or Professional Use

For vehicles used in demanding conditions, modified for performance, or subjected to frequent heavy load or towing—common uses for an Expedition—managing crankcase pressure and oil contamination becomes more important. An effective oil separator can be part of a strategy to maintain engine efficiency and longevity under such stresses. It is a common installation for enthusiasts and professionals looking to optimise engine breathing and reduce maintenance intervals related to intake valve or intercooler fouling.

Everyday Home Use

For the standard 2018-2020 Ford Expedition used as a daily driver or family vehicle, this component offers a preventative maintenance benefit. By helping to reduce the amount of oil vapour and contaminants entering the intake system, it can contribute to cleaner engine operation over the long term. The choice of colour finish allows owners to add a subtle customised touch to the engine bay during installation.

Benefits and Buying Value

The value of this product lies in its targeted application, durable construction, and the functional benefit it provides for the specific vehicle platform.

Reuse and Low Maintenance

Once installed, an aluminium oil separator like this is designed as a long-term component. Many similar units are constructed to be serviceable, allowing for internal elements to be cleaned and the unit reused indefinitely, which adds to its long-term value. The aluminium body requires minimal maintenance beyond occasional external cleaning and checking of connections.

Why Choose This Product

This oil separator kit is a defined solution for owners of 2018-2020 Ford Expeditions seeking an aftermarket option for this component. The key reasons to consider it are the confirmed vehicle compatibility, the practical and durable aluminium alloy construction, and the availability in multiple colours. It provides a single-source kit for the installation, removing the need to source additional parts separately.
