Polished finish. Comes complete with everything need to fit including step by step instructions. Please note. This kit can only be fitted when the vehicle has been fitted with a front mount air to air intercooler conversion i.e. Airtec, Pro alloy or similar. Supplied with its own fan assembly for extra cooling. Why fit a Turbo cooler? The Focus RS runs a water cooled Turbo, which in turn is great for the Turbo but not for the cooling system! The water comes into the turbo at normal engine temperature then exists the turbo at considerably higher temperature. By fitting a turbo cooler, you cool down this super heated water before it goes back into the cooling system and helps prevent temperature spikes when on boost.
