Precise boost management is essential for extracting reliable power from the factory turbocharged 1.6-litre engine. Prevent boost leaks and ensure sharp pressure holding between gear changes by upgrading the notoriously weak factory recirculation valve. We supply high-performance Turbo Dump Valves, also known as diverter valves or recirc/recirculation valves, ensuring your forced induction system operates flawlessly under the elevated boost pressures of modern tuning.
