T4 Turbo Inlet Flange ( Divided Inlet)- T304 Sta

The T4 Turbo Inlet Flange (Divided Inlet) in T304 stainless steel is a precision turbocharger inlet manifold component designed for high-performance engine builders and turbo system fabricators. This divided inlet design allows for dual-entry configurations, enabling optimized airflow distribution across multiple cylinders in custom boost applications. Fabricators and engine shops rely on this flange to create efficient, responsive turbo induction systems that maximize spool characteristics and reduce intake runner length asymmetries in complex engine builds.

Machined from T304 stainless steel, the T4 Turbo Inlet Flange delivers superior corrosion resistance and thermal stability compared to mild steel alternatives, making it ideal for aggressive boost applications and extended high-temperature engine operation. The 0.5-inch flange thickness provides structural rigidity necessary to seal reliably against turbocharger compressor housings while resisting warping under thermal cycling and boost pressure. The divided inlet geometry creates two separate entry ports, enabling manifold designers to balance flow paths and reduce turbo lag while maintaining precise runner angles for efficient combustion chamber filling in high-RPM, high-boost scenarios.

This component is essential for builders constructing custom turbocharged engines across automotive, marine, and light industrial applications where OEM manifold geometry proves limiting. The T4 mounting flange standard ensures compatibility with a wide range of turbocharger compressor housings, and the stainless construction is welding-friendly for manifold fabrication and integration with custom intake systems. Installation requires precise alignment and a quality gasket seal; professional fabrication shops typically machine mating surfaces and use high-temperature gasket material to ensure leak-free, pressure-tight operation under sustained boost levels.
