Ford is offering Fiesta ST customers in the UK a unique opportunity to buy performance upgrades for their cars through a choice of two special dealer-fit options.

Increase power to 185 bhp

Thanks to a new association with Mountune, a motorsport specialist run by Roush UK, the Ford Fiesta ST can now be boosted to 185 bhp. The kits do not affect the vehicle warranty and are available from selected Ford dealers (London, Bristol, Birmingham, Warrington and Castleford) from March 1 2008 onwards.

There are two packages available, Mountune Performance Stage 1 package retails at GBP 1,435 and consists of a high-flow air induction system, high performance exhaust system including high flow catalyst and tubular manifold and re-calibration of the 2.0 liter Duratec ST engine resulting in a power increase to 165 bhp. The Mountune Performance Stage 2 package costs GBP 1,838 and adds new camshafts and valve springs to delvier 185 bhp.

The Ford Fiesta ST was the first Ford to carry the Sports Technologies badge and made its debut at the 2004 Geneva Motor Show. Later in 2008 Mountune will offer additional kits for other Ford ST models.
