This do88 silicone hose kit replaces the complete radiator and cooling circuit hoses on the Audi S4 and RS4 2.7 biturbo with high quality silicone reinforced by three to five fabric layers depending on inner diameter. It covers the upper and lower radiator hoses along with the smaller expansion tank, bleed, heater, auxiliary water pump, coolant pipe, and oil cooler hoses that harden and crack with age, finished in black. The original quick connections are reused, and a matching do88 clamp kit is available separately.
