ATINT34/BBP - The Stage 4 Intercooler Upgrade is yet another successfully proven performance upgrade from AIRTEC at AET Motorsport.
The Stage 4 extracts the maximum amount of gains from the 300+ bhp Ford Focus ST MK2s with the 2.5" Hard Pipe upgrade replacing the standard 2.0" restrictive boost pipes.
Gains of 11.8 bhp and 9 Ib/ft torque have been witnessed with the 2.5" however these gains will vary depending on the spec of your ST.
Intercooler spec:
  • Pro-Series Black
  • Strongest Intercooler available, backed up by our 3 year warranty
  • All Pipe's have swayed ends to stop the pipes blowing off
  • Smooth flow end tanks, no welds, means no leaks
  • Airtec logo brackets
  • Air-Ram Scoop, forces Air directly into core of intercooler
  • Huge high flow 60mm core, lower ACT Temps
  • Increased BHP & torque Figure
Please note that the Pre-facelift ST has a different radiator compared to the facelift & RS. This makes the left hand pipe very tight against the radiator cradle & boost hose, it's recommend that you remove the radiator cradle bolt, levering the cradle to the right and re-drilling a new hole & then replace bolt.
Fitting takes 1 - 2 hours. If you require fittings please contact us on the following details:
