The SD Hoses Silicone breather hose (part no. SD22) has been designed to replace the standard restrictive OEM hose on the Volkswagen MK4 Golf or Seat Leon 1.8T.
The hose is constructed to provide a constant radius reducing restriction throughout the whole piping.
The hose is made from high-quality 6 layer mutli-ply silicone. It is available in Black, Red, White or Blue to compliment the signature colours of the Golf MK4 GTIrange.
