Ford Performance releases Focus ST kit in collaboration with Mountune
In the United States, Ford Performance has close ties with tuner company Mountune. As a result of that, they can offer performance upgrades for their products while still retaining their factory warranty- a testament to Ford’s belief in the reliability of the components.
The idea of a street-legal, reliable, largely stock 2.0-liter four-cylinder engine making nearly 300 lb.-ft. of torque might have seemed ludicrous 10 years ago, but the components of the MP275 Focus ST performance upgrade not only combine to produce up to 296 lb.-ft. of torque with 93-octane fuel, they are designed for maximum reliability as well.
When the parts installation and tuning is performed by an authorized Ford Performance technician, Focus ST retains its factory warranty – a huge benefit for any customer looking to get the most out of the ownership experience. The heart of the system is a performance ECU calibrated to deliver a more aggressive engine mapping program, including a quicker throttle response, without compromising durability. Power spikes from 252 horsepower to 275 horsepower.
Unlike many aftermarket kits that compromise reliability and driveability on the street while also hampering emissions, the Mountune system keeps Focus ST street-legal in all 50 states. This is a big plus point, because in certain states like California where emissions testing is mandatory, it can be difficult to run a modified car legally.
