44 MM WasteGate Inlet Flange

The 44 MM WasteGate Inlet Flange from VIBRANT PERFORMANCE is an essential component for turbo and supercharger systems that demand precision boost control. This inlet flange connects the wastegate actuator to the exhaust bypass valve, allowing excess boost pressure to vent safely and maintain target PSI levels. Whether you're running a street turbo build, a competition engine, or upgrading an OEM turbocharged platform, a quality wastegate inlet flange ensures consistent boost response and protects your engine from over-pressurization.

Engineered to OEM specifications, this 44 MM inlet flange is manufactured to tight tolerances and designed for direct bolt-on installation to most aftermarket wastegate housings. The 44 MM bore diameter matches common wastegate inlet ports, ensuring proper signal flow and minimizing restriction that could delay boost venting response. VIBRANT PERFORMANCE's design prevents boost creep—a common problem on modified vehicles where boost pressure rises above target during sustained acceleration—by providing a clean, unrestricted path for pressurized air to reach the wastegate diaphragm. Compact at just 0.2 lbs and engineered aluminum construction, this flange resists thermal cycling and corrosion in high-temperature turbocharged environments.

This inlet flange benefits anyone serious about turbo system reliability—from weekend track enthusiasts to engine builders standardizing boost control on LS, small-block Chevy, Ford EcoBoost, and Nissan platforms. Installation requires only basic hand tools and fits most universal turbocharged setups where a 44 MM wastegate source is available. Verify your wastegate housing bore diameter and inlet port configuration before ordering; this component is typically paired with a quality adjustable wastegate and boost controller to fine-tune performance. Proper installation of the inlet flange directly impacts spool response, peak boost stability, and long-term engine safety on modified vehicles.
