Whilst the original chargecooler works well on standard car, as soon more boost is added from a simple remap, the original Ford radiator struggles to sustain safe temperatures, which in turn can make the car run slower as charge air temps increase and the ECU is forced to restrict power to combat it. 

Our Mk1 Focus RS chargecooler radiator upgrade features a 70mm core, which is 30mm bigger than the OEM radiator. This increases capacity to 9.7 litres, compared to tee original radiator, which measures 5.5 litres. This gives an overall increase in capacity of 76%.

Best of all, it’s a direct fit with no extra modifying needed and simply reuses all the original fixings and fittings.
