Unlike the standard rubber OEM hoses which deteriorate over time and collapse when under pressure, our hoses are constructed using a high quality silicone Polyester or Nomex compound. They are further reinforced with a polyester layer to provide a more rigid structure to prevent collapse of hose under high boost conditions whilst sustaining pressure which is essential for the smooth delivery of power and quicker turbo spool resulting in increased performance and improved throttle response.
