Boost Hose Upgrade Kit [Mk3 Focus RS]

Silicone hose colour
Light Blue

The mountune Boost Hose Upgrade Kit for mk3 Focus RS features wire-reinforced, nomex lined smooth bore hoses, which are available in three colours to complement all Focus RS vehicle colours.

During extensive durability testing, turbo outlet temperatures were recorded in excess of 180º, which is the safe operating limit for OE and polyester-lined silicone hoses. The mountune boost hose kit utilises a nomex lining on both hot-side hoses, which operate reliably upto 250º, giving substantially improved resistance to failing when power output is increased beyond standard.

This kit is also compatible with the OE intercooler and systems that use the original intercooler charge pipes.


  • Stainless wire-reinforced
  • Nomex lined
  • Easy installation (no drilling required)
  • Lifetime warranty
  • Hoses available in three colour options: mountune black and yellow, light blue or grey
  • Advised to fit with optional Hose Clip Kit (Boost)
