Pro Hoses Focus MK2 Hot Side Boost Hose
Replacement silicone hot side boost hose for Focus MK2.
This can be made to order to fit different variations of intercooler and boost pipework.
The following options are available:
- Stock ST225 Intercooler – 2″ intercooler outlet with 2″ OEM lower boost pipe
- AIRTEC Stage 3 ST225 / Stock (or AIRTEC) RS Mk2 Intercooler – 2.5″ intercooler outlet with 2″ OEM lower boost pipe
- AIRTEC Stage 4 ST225 / Stock (or AIRTEC) RS Mk2 Intercooler with Big Boost Pipe – 2.5″ intercooler outlet with 2.5″ lower boost pipe
The Focus ST225 standard intercooler has 2″ outlets and uses a 2″ lower boost pipe. The hot side hose to suit this option is not kept on the shelf and is made to order – please allow up to 10 working days for delivery.
Option as seen in the picture is to fit all RS intercoolers (standard and AIRTEC) with 2.5″ intercooler outlet and the OEM 2″ lower boost pipe.
We can make this hose as a replacement for the AIRTEC 2.5″ Big Boost Pipe Kit (includes AIRTEC ST225 Stage 4 Intercooler) which will fit with 2.5″ intercooler outlets and 2.5″ big lower boost pipe.
If fitting to a Focus ST225 – this can be fitted with the standard ST radiator however, for better fitment, we would recommend fitting with RS radiator to prevent any rubbing.
Please note: Kawasaki Green is a brighter colour than Ultimate Green (Focus RS Green)
