Halfway through its production cycle, the third-generation Ford Focus received a facelift that included changes to the exterior, cab, and engine options. The updated vehicle featured thinner, more angular headlights and a sporty grill that made its way into several other models in the company’s lineup. Meanwhile, the vehicle’s interior featured a cleaner dashboard with less buttons, a new touchscreen menu, and higher-quality materials. Ford also sought to improve performance in this iteration. Upgrades to the vehicle’s chassis and steering made for better road-holding capabilities and a more pleasurable overall driving experience. New engine options helped in that department, as well. In 2016, Ford launched the most powerful version of the Focus yet—the Focus RS, featuring an updated version of the 2.3L EcoBoost engine used in the new-generation Ford Mustang. The RS also featured the company’s new “Drift Mode” torque-vectoring technology, designed to make slides easier by sending disproportionate power to the rear axle. Here are some of the most popular stock, upgrade, and aftermarket replacement parts for 2014-18 Focus models.
