The factory turbocharger on the 2.5 TFSI TT RS 8S is highly capable, but as you increase boost pressures with aggressive software tuning, the supporting hardware can quickly become a weak link. We stock complete upgraded turbochargers for owners looking to build massive DAZA power. For stock turbo setups, swap out the failure-prone factory diverter for an uprated turbo dump valves (or diverter valves) unit to ensure your engine holds maximum pressure securely. You can also browse our misc turbo parts for the essential hardware, lines, and fittings needed for a reliable forced induction setup.
