  • AIRTEC
  • Pace
  • Pro-Alloy

The Pro Hosed 2.5″ cold side pipe upgrade to replace Ford’s restrictive 2″ boost pipe. The original Ford pipe also has joins in the middle where as the Pro Hoses is made in one-piece for super smooth flow.

Fitting takes 0.5 to 1 hour.

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
