AIRTEC Stage 4 Intercooler Upgrade for Focus ST MK2

Designed & Proven to extract maximum gains from your 300+ bhp ST, this kit would compliment the DreamScience Turbo X upgrade or a similar Big Turbo conversion.

2.5" Hard pipe upgrade removes fords 2.0" restrictive boost pipes. We saw gains of 11.8 bhp & 9 lb/ft torque increase's over the standard ford pipes, these gains were achieved by simply bolting on the big AS 2.5" Boost pipe kit!

Important Note. The Pre-facelift ST has a different radiator compared to the facelift & RS, this makes the left hand pipe (Inlet side) very tight against the radiator cradle & boost hose, we recommend removing the radiator cradle bolt, levering the cradle to the right and re-drilling a new hole & then replace bolt. Its very simple and Easy to do, but is necessary to give you extra clearance for the bigger 2.5" pipe, if you are still not happy with fit we would recommend fitting a RS radiator, not required to get the power you want, just makes cold side hose fit nicer.
