Ford Focus RS Mods and Aftermarket Performance Parts

History of the Mk3 Focus RS

The Mk3 Ford Focus RS, introduced in 2016, is a high-performance legend that elevated the hot hatch game to new heights. With a rich heritage dating back to the original Focus RS in 2002, the Mk3 model continued the legacy with a powerful 2.3-liter EcoBoost engine, producing a staggering 350 horsepower and 350 lb-ft of torque. This immense power was delivered to all four wheels through an advanced All-Wheel-Drive system, propelling the car from 0 to 60 mph in just 4.6 seconds. The Mk3 Focus RS set a new standard for hot hatch performance, earning its reputation as a true driver’s car.

In addition to its remarkable performance, the Mk3 Focus RS boasted a range of advanced features and technologies. It introduced an innovative “Drift Mode” that allowed skilled drivers to engage in controlled drifts, showcasing the car’s dynamic capabilities. The interior was both sporty and practical, with Recaro bucket seats, a user-friendly infotainment system, and plenty of cargo space. These features, combined with its bold and aggressive exterior design, made the Mk3 Focus RS a true standout in the hot hatch segment. It remains an enthusiast’s dream, offering a perfect blend of power, precision, and practicality, and cementing its place in Ford’s storied performance history.

Filters and Intakes

Replacing the factory intake and airbox with the COBB SF Intake System will greatly reduce pre-turbo restrictions. When a restriction is removed, it allows the engine to be more efficient while also enabling it to make more overall power! The higher flowing intake also makes turbo and bypass valve noises more audible.

Intercooler

The COBB Front Mount Intercooler for the Focus RS is the easiest way to drastically improve power when coupled with tuning from the Accessport. Even when stock, the factory FMIC can be overwhelmed with heat soak. By using a 57% larger core with streamlined piping, your Focus RS will come alive with charge air that’s up to 100 DEGREES COOLER. This is the single best hard part modification for your Focus RS.
