This 034 Motorsports turbo inlet hose replaces the restrictive factory rubber boot with a smooth, 4-ply reinforced silicone design. It resists collapse under vacuum, improves airflow, and sharpens throttle response for your Audi S4 or S6 C4 (1992-1996).

Includes new hose clamps for a secure installation, and it fits most turbochargers with ~2.25" compressor inlets. A direct upgrade for the OEM part 034133357S.
