WG45 Inlet Weld Flange

The WG45 Inlet Weld Flange is a precision turbo inlet component engineered for high-performance engine builders and turbocharger system integrators. This steel weld flange serves as the critical interface between intake plumbing and turbocharger housings, directing compressed air flow with minimal turbulence. Designed for durability and reliable operation under elevated boost pressures, this component is essential for anyone building or upgrading a turbocharged power plant.

Manufactured from robust steel in its natural finish, the WG45 Inlet Weld Flange is built to withstand thermal cycling and mechanical stress inherent in forced-induction applications. The weld flange design allows direct integration into custom intake manifold fabrication, eliminating the need for threaded connections that can loosen under vibration. Steel construction provides superior heat resistance compared to aluminum alternatives, making it ideal for applications where inlet temperatures rise significantly. The flange's compact profile—measuring 7.9 x 3.9 inches with a 0.8-inch thickness—ensures proper fitment in tight engine bay environments without compromising structural rigidity.

Fabricators, turbo builders, and performance enthusiasts will find this inlet weld flange indispensable for custom turbo installations on both street and competition engines. This component is particularly suited for applications requiring Class 1 or Class 2 boost levels where permanent welded connections are preferred over removable fastened assemblies. Installation involves TIG or MIG welding to custom intake piping, ensuring an airtight seal that optimizes boost response and prevents compressor surge. Whether you're building a street machine or a track-focused turbo system, the WG45 inlet weld flange delivers the reliable, durable performance expected from purpose-built turbocharging components.
