Replace the restrictive OEM plastic cold side boost pipe with the ProHose Cold Side Boost Pipe for your Ford Focus ST225. You will benefit from higher HP and quicker throttle response and won’t have to worry about the OEM plastic one eventually tearing, causing a boost leak. The ProHose Cold Side Boost Pipe can be optioned with the symposer fitting for those who want to run an external BOV (who have changed their OEM turbocharger or blanked off their OEM BOV on the compressor housing) or without.
This Cold Side Boost Pipe will fit the stage 1 & 2 Airtec intercoolers or one that has the OEM location.
** Airtec normally stocks Gloss Black, Race Red, Performance Blue. Other colour hoses will be made to order with an additional 2-4 week lead time.
