Show original supplier description
The Ford Performance M-14204-FSTA is a calibration and spark plug kit engineered to enhance the performance of the 2013-2018 Ford Focus ST models equipped with the 2.0L EcoBoost I-4 engine. This kit includes a performance calibration tune and a set of four spark plugs that are two steps colder than stock. To achieve its maximum gains and prevent issues like spark knock or detonation, this calibration requires the use of premium fuel, with 91 octane or higher recommended, and 93 octane preferred. The tuning is designed for an otherwise stock vehicle and can provide a significant torque increase, up to 90 lb-ft at 2800 rpm on 93 octane fuel, with substantial gains continuing up to 4200 rpm.
