Technical Data


Full 70mm coldside hose for the Focus RS Mk2!

This boost pipe starts with a 63mm outlet so that it will connect to most brands of intercooler including the standard OEM intercooler. It then expands up to 70mm for the rest of the hose until the throttle body where it can either be supplied with a 63mm hose to fit the standard throttle body or with a 70mm hose to fit an aftermarket uprated throttle body. Please select the option that suits your car.

Most uprated boost hoses are 2.5 inch (63mm) and the standard ford pipework is 2″ (60mm). This boost hose is 70mm allowing faster more free flowing air.

Will fit With the following intercoolers:

  • AIRTEC Motorsport Stage 1 & Stage 2
  • Pace
  • Pro-Alloy
  • Forge
  • Mountune
  • Ford OEM

Please note: 

  • When fitting, the hose must be angled a certain way to avoid contacting the plastic supports on the radiator 
  • To gain further clearance against any sharp edges on the radiator, we recommend trimming the radiator’s excess plastic. Please see fitting note here: COLD-SIDE-BOOST-HOSE-FOR-FORD-FOCUS-ST-AND-RS
