Ford has released official Mountune power upgrades for its Focus and Fiesta ST models.
Costing from £1225 for the Focus ST upgrade and £599 for the Fiesta ST, and taking under 90 minutes to install, the upgrades significantly improve power and torque on both models.
The Focus ST upgrade - which includes a cast alloy inlet duct, high-flow air filter and a larger intercooler - boosts power from the 2.0-litre EcoBoost engine to 271bhp, while torque is improved to 295 lb ft. The upgraded car can sprint from 0-62mph in less than 6.0sec, more than half a second faster than the standard Focus ST.
Upgrades for the Fiesta ST - based around a remodelled air box with a new secondary inlet duct - improve power to 212bhp and torque to 236 lb ft. Sprint time for 0-62mph falls to 6.7seco, compared to 6.9sec on the standard car.
Both upgrades can be applied from 120 Ford-appointed Mountune dealers.

"based around a remodelled air box with a new secondary inlet duct "
So that's £600 for a new air box, duct and fitting. sounds a bit expensive
Also, something else must be done as replacing those 2 parts wouldn't give another 30 odd horsepower

£16,995 Fiesta ST from 179bhp to 212bhp, thanks to an ECU tweak and a reworked air intake, including a secondary inlet duct and high-flow filter.
It’s worth noting the improved figure is developed during the Fiesta ST’s temporary overboost period under full-throttle
As both upgrades are covered
As both upgrades are covered by Ford's Warrenty they seem a 'no brainer'.
