Due to this hose being oversized and the limited space available for fitting, you will find an obstruction caused by a metal coolant pipe which runs close to the turbo intake pipe, you would be required to unbolt the metal coolant pipe from its mounting bracket and move slightly away from the engine to accommodate the oversized hose. Professional installation is recommended.

This pipe will fit the standard K03 and K03S turbos with a 45mm inlet, and a 70mm Standard MAF end fitting.

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.
