2016-2018 Focus RS Performance Parts & Accessories

How to make the most our of your RS

The performance-oriented RS brings a lot to the table with its 2.3L EcoBoost pumping out 350 horsepower and 350 lbs/ft of torque. What's even better is how easy it is to modify for more power, better handling and unique styling. But where do you start? That's where Stage 3 comes in. If you aren't sure where to begin with your RS build, the first thing you want to do is read this quick guide that can help you find a solid direction for your hot hatch build.

Lowering Springs Improve Handling and Styling

It's really, really hard to wrong with lowering springs. This proven suspension upgrade will lower your RS just a tad to improve cornering and handling, and you'll love the aggressive, track-inspired look. Most importantly, lowering springs are relatively affordable. Check out our selection of Focus RS Lowering Springs here.

Bring out the Beast with COBB's AccessPort V3 Tuner

While 350 HP and equal numbers torque is nothing to scoff at, more power is always better. That's why COBB's AccessPort V3 tuner is one of the most popular upgrades for the Focus RS, period. This intuitive programmer comes loaded with software and features that make tuning, driving, and caring for your Focus RS a breeze. The Accessport V3 features octane-based performance tunes that can increase horsepower by up to a maximum of 13% and torque output by 13% all without the need for any "hard" performance parts at all. Each Accessport V3 can also accept custom tune and maps from qualified Accessport tuners to help you run extremely powerful modifications like aftermarket downpipes and turbocharger upgrades without damaging your RS's engine.

Upgrade your Exhaust System for Improved Sound and Performance

Thanks to the RS' electronic balancing valve, upgrading your exhaust system can come with a fair share of hassle. Thankfully though, our friends over at MBRP have you covered with their Black Series 3" cat-back exhaust kit. The Black Series Focus RS cat-back exhaust system features larger tubing than stock, a more aggressive muffler design, and most importantly a valve simulator to avoid issues with Ford's electronic exhaust valve assembly.

Cold Air Intakes Increase Horsepower and Torque

Cold air intake kits are some of the easiest and most affordable ways to increase horsepower and torque, which is what makes them such popular upgrades for every performance enthusiast. Mishimoto's Performance Intake System goes in place of your factory intake system and delivers dyno-proven power gains up to +12WHP and +15WTQ. The air filter is positioned near the front of your Focus RS for optimal airflow and lower intake temperatures. This is a complete upgraded intake system that replaces every core component in your factory setup, including the airbox and the intake pipe.
