These external wastegates are built to Stinger Performance specs to perform better than the lower cost alternatives that leak through the valve stem, greatly hampering performance. These wastegates incorporate a valve seal just like a cylinder head which seals the valve stem to prevent leakage. Cast Stainless Steel and Polished Aluminum construction. They come with a 8 psi internal spring. This means 8 psi is the minimum amount of boost you can run. You can still raise boost up to 25+ psi with an adjustable boost controller or by changing wastegate spring. 6mm ID hose fits tightly on the boost ports. 

Includes:

• Wastegate
• 8 psi spring
• 2 Stainless Flanges
• 2 Gaskets
• 2 Banjo Bolt/Nipple Assemblies
• 1 Valve Seat
• Stainless Hardware
