A full silicone coolant hose set for the 1.8T 20V engine in the 8L Audi S3, 8N TT and Seat Leon Cupra R, covering the upper and lower radiator hoses, heater hoses, auxiliary water pump hoses, oil cooler hoses and bleed hoses. Every hose is made in high quality silicone with three to five armoured layers depending on inner diameter, so it holds cooling system pressure and under-bonnet temperature long after the original rubber has gone hard. The set replaces OEM 8N0121051B, 8L9121101A, 8L9121053A, 8L9121073D, 8L9121157D, 8N0121088, 8L9121096C and 8L9121086D.
