This high quality reinforced silicone hose kit replaces the 4 intercooler hoses in the engine bay listed below. Constructed from thicker 5.4mm 4-ply reinforced silicone to prevent the hose from collapsing under boost. The hoses fit MINI Cooper S MK2 R55/R56/R57 (including JCW and Clubman Cooper S) models with the N14 engine only, it will not fit N18 engines.

The kit removes the T-off to the standard noise generator on the cold side, improving performance by reducing the volume of air for the turbo to compress in the intake system. The stock resonator on the hot side can either be retained, or replaced with an aluminium straight pipe which is available as an optional extra in the product options.

  1. Turbo to Resonator Hose
  2. Resonator to Intercooler Inlet Hose
  3. Intercooler Outlet to Hard Pipe Hose
  4. Hard Pipe to Throttle Body Hose (replaces two original hoses and the plastic noise generator T-pipe)

Hose Clamps:

The kit is available with a full set of hose clamps using the options above. The three types of clamp we offer are shown below, but not all options will appear for some kits due to size limitations:

Stoney Racing Stainless Steel Worm-Drive Clamps, Black Coated Spring Clamps and Stainless Steel T-Bolt Clamps

Spring clamps * Not available for this product *

Worm-Drive clamps have slightly less evenly distributed clamping force as the Spring type clamps, but they are still a good quality clamp and usually easier to fit/remove in the tight confines of an engine bay. Being 100% stainless steel they do not rust, so we recommend this type of clamp if you are concerned about the appearance of your engine bay.

T-Bolt clamps are the most heavy duty clamps we supply, and are also 100% stainless steel to prevent rust. However they are much more expensive and, like the Worm-Drive clamps provide a slightly less evenly distributed clamping force than the Spring clamps. For this reason we recommend using them for Turbo applications (intercooler/intake hoses) where high boost can cause hose blow-off's and the additional clamping force is useful. Some customers like to use T-Bolt clamps for all hoses on their vehicle however so we offer them as an option for most of our kits.

For some vehicles the original clamps can be reused so we also offer our kits without clamps, but please be aware our silicone hoses are slightly thicker than the standard hoses so in some cases the original clamps may be too small.
