Boost Hose Upgrade Kit - RS

The mountune boost hose upgrade kit for mk3 Focus RS features wire-reinforced, nomex lined smooth bore hoses, available in three colours to compliment 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.

  • Easy installation (no drilling)
