Ford's RS tuning firm has teamed up with Mountune Performance, a motorsport company owned by Roush, to offer two stages of tuning kit for the Fiesta ST.The Stage 1 kit costs £1,435 with fitting an additional cost, and includes new air-induction and exhaust, and an engine tweak to the 2.0-litre Duratec engine to produce 162bhp. Stage 2 costs £1,838 (also excluding fitting), and comes with the same upgrades as the basic pack plus new camshafts and valve springs, with power boosted to 182bhp.Both kits can be retro-fitted at certain Ford dealership, come with a minimum 12 month/12,000 mile warranty, and do not affect the car's standard manufacturer warranty. Ford will be hoping the new tuning packs will boost interest in the Fiesta ST before it is replaced with the new Fiesta, due to go on sale in 2009. You can also expect to see more of the Mountune tuning packs on other Ford models throughout 2008. We'll take a 250bhp Focus ST, thanks.
