Turbo inlet flange designed for T4-divided turbine housings (such as Garrett GT3788, GT4088R, GTX4088R, GT4094R, GT4202R, GT4294R, GT4508R, GTX4508R). CNC-machined from ½″ (12 mm) thick 1018 mild steel, this flange ensures rigidity and resistance to warping under heat. Four drilled bolt holes (not threaded) support bolt-and-nut installation for secure mounting to turbine housing or custom manifolds.

Port dimensions are optimized to match common T4-divided inlet geometry, preserving flow integrity and reducing turbulence at the turbine entry.

• Compatible with T4-divided turbine housings (e.g. Garrett GT3788, GT4088R, GTX4088R, GT4094R, GT4202R, GT4294R, GT4508R, GTX4508R)
• CNC-machined from ½″ thick 1018 mild steel
• Four drilled bolt holes for M10 bolts (nuts required)
• Port opening designed for optimal flow into divided turbine
• Flat and uniform surface suitable for welding or gasket sealing
• Sold as a single flange—bolts and gasket not included
