The do88 turbo outlet hose for 1991–1997 Audi S4, S6 and A6 2.2T (C4 AAN) in blue replaces the outlet plumbing from the turbocharger for these models. Intended to match the original routing on the Audi 2.2T C4 applications, it restores the post-turbo charge-air path. Choose this vehicle-specific hose when the factory outlet line is deteriorated to reestablish proper boost transfer to the intercooler.
