Forge Focus MK3 ST intercoolerThis intercooler for the Ford Focus ST250 is a real example of British Engineering at its best. Designed with a greater surface area and cooling efficiency than the stock core this is a real performer. Our core maximises all the space the Ford designers failed to take advantage of and is combined with an expertly engineering hard pipe kit to maximise the flow rates and ensure minimum resistance and pressure loss. We have seen excellent test results.
