The Focus ST has turned out to be one of the bigger surprises of Ford's recent lineup. A front wheel drive hot hatch from an American car company topped off with a direct-injected, turbocharged engine -- what's not to like? Even better, the aftermarket has exploded with a ton of new performance parts that can make these great little cars even better. Whether you're looking for better handling, increased power or just a solid audio system, all of our parts come from the most famous names in the performance parts world to deliver reliable performance and aesthetic upgrades for the life of your car.
Like every single turbocharged car since the turbocharger made its way from planes to cars, the 2013 to 2017 Focus STs come from the factory undertuned to help extend the life of the turbo and keep that EcoBoost 2.0L from working too hard. Fortunately with the right cooling upgrades, a PCM tuner can be a safe way to increase power without doing any irreparable damage to your 2.0L Ecoboost.
You really can't go wrong with COBB when it comes to tuning your ST. They have a stellar reputation for quality and results, and their golden child, the Accessport V3, gets absolutely rave reviews from just about everyone who owns one. The versatile and intuitive tuner effortlessly mounts onto your center console next to your steering wheel so as not to distract you while driving.
Underlying its relatively simple exterior appearance is a high-powered device loaded with software and features that make tuning, driving, and caring for your aggressive 2.0L EcoBoost Focus ST that much easier. The Accessport V3 features octane-based performance tunes that can increase horsepower by up to a maximum of 15% and torque output by 31% all without the need for any "hard" performance parts at all.
Remember how I mentioned "the right cooling upgrades" in regards to accommodating the increased power demand you get with aftermarket tuning? This is a crucial step in ensuring that your ST doesn't poop out on the track and a cold air intake is also a great companion to a PCM tuner. If you want to keep engine temps down and horsepower up, check out our selection of Focus ST Cold Air Intakes.
It's hard to beat a good tuner/CAI combination, and once you've got your own setup you'll be well on your way to being king of the tracks and the street. Also check out our selection of Focus ST Exhaust Systems if you're looking for an exhaust sound that does your ST justice. We threw on Borla's Touring Exhaust Kit which gave our 2016 ST project car a louder, more crackly exhaust note and improved exhaust flow.
