Ford Focus RS Mountune upgrade announced

Official Ford tuner Mountune releases kit for Ford Focus RS hot hatch.

FORD Focus RS owners with a penchant for one-upmanship are in luck: Ford’s official tuning arm, Mountune, has announced an upgrade for the already bonkers 257kW hot hatch.

Save your money, though, for while the amped performance kit is available in the US and the UK, it hasn’t yet been confirmed for us.

The Phase 1 package includes hoses, roll restrictors and 19-inch Oz Racing wheels, improving visuals and airflow.

Oh, and it all comes with the benefit of a factory warranty.

The bad news for Aussie owners is you may not be able to get the package just yet.

Mountune has previously offered upgrades on both the Ford Focus and Ford Fiesta ST models in Australia.

The upgrades come in the form of an ECU flash, uprated turbo recirculation valve and Mountune’s RS induction kit that includes an alloy crossover duct and high-performance silicone hoses to improve engine breathing by 11 per cent versus the factory-fit pipes.

Priced in the UK from the equivalent of $1545, the Mountune Phase 2 performance package takes about 1.5 hours to install.

The relatively modest performance upgrade is believed to be due to limitations with the RS’s tricky diffs.
