AIRTEC Stage 3 Intercooler Upgrade for Mk2 Focus ST (RS SPEC HOSES)

< Back




We have taken our huge Focus RS intercooler and modified it to fit with the ST bumper & then taken our massive 2.5" cold side Pro Hoses (intercooler to inlet manifold) and a Pro Hoses boost pipe from intercooler to ST standard metal pipe, making this kit the best value for money option for 300+ bhp Focus STs.
Designed & proven to extract maximum gains from your 300+ bhp ST, this kit would compliment the DreamScience Turbo X upgrade, Jamsport or a similar big turbo conversion.
Our RS into ST performance & cooling kit has been rolling road tested (tests caried out @ AMD Essex)
2.5" hard pipe upgrade removes Ford's 2" restrictive boost pipe (cold side). We saw gains of 10bhp+ & 9lb ft torque increases over the standard Ford Gains will vary depending on spec of your ST.
Intercooler spec.
  • Air ram Scoop, forces Air directly into core of intercooler
  • Huge high flow 60mm core, lower ACT Temps, 
  • Smooth flow end tanks, no welds, means no leaks
  • AIRTEC logo brackets
  • Increased BHP & torque figure
  • Pro-Series black
  • Backed up by our 3 year warranty. 
  • Cold & hot side Pro Hoses joiners, available in choice of colours

Fitting takes 1 - 2 hours depending on mechanical skill & tools available

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 re-fitting the bolt. It's 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, but makes cold side hose fit nicer.
Need even more power? Take a look at our Stage 4 AIRTEC intercooler cooling package, which includes full 2.5" boost pipe kit. 
Please Note: Kawasaki Green is a brighter Green than Ultimate Green (FRS Green)
