• 2013 Ford Focus ST by Roush Performance

LISTEN 02:21

Ford tuner extraordinaire, Roush Performance, is most known for its programs for the Mustang. But every so often, the tuner takes a turn and works on a different Blue Oval model.

Take for example the Ford Focus ST.

The new program for Ford’s resident sports hatchback is available for 2013 models and beyond. It comes with a plethora of new components that give the Focus ST some pretty impressive aesthetic and performance credentials.

The most impressive thing about this program is that despite what you already see, Roush Performance is still working on other parts for the Focus, including suspension components, powertrain control module (PCM) upgrades, together with wheels and tire combos, and interior and exterior accessories.

For now, what it has already speaks to its impressive work on the pocket rocket of a sports hatchback.

New Exhaust

Always one to build programs slowly but surely, it’s not a surprise that Roush Performance is taking it easy with the Focus ST. For now, one of the key additions to the sports hatchback is a new cat-back high-performance exhaust system. We expect this free-flowing exhaust to go hand-in-hand with future performance upgrades down the road, particularly a cat-forward system and a new free-flow cat.

Cold Air Intake Kit

If you’re going to update how effectively the Focus ST exhale, via its new cat-back exhaust system, you also have to help it breathe more deeply. This is where this cold-air intake system comes in to play. It not only eliminates the restrictive air-intake system on the stock Focus ST with a freer-flowing one, but it also injects cooler air into the intake system. Cooler air is denser, which causes the fuel to burn more effectively, thereby increasing performance.

Net Increases

A cat-back exhaust system and a CAI system are not enough to really bump the Focus ST’s horsepower output much. However, these modifications will give the ST a better sound and improved throttle response – always a nice place to start. We’ll bring you more details as Roush adds to this base setup.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
