Another failure prone item in the cooling system on the 1992-1995 audi S4/S6 is the plastic thermostat housing that comes from the factory on these cars. An easy upgrade used to be to swap on the OE housing from the early 5k turbo models.. until audi decided to make those NLA. INA Engineering has reproduced this housing in beautiful billet aluminum. finished in clear anodize for a lifetime of service.
