T25/T28/GT25 Turbo Inlet Flange (1/2in thick)

The T25/T28/GT25 Turbo Inlet Flange is a precision engine component engineered for forced-induction systems running Garrett and Borg Warner turbos. This half-inch thick steel flange serves as the critical connection point between the turbocharger compressor outlet and the intake manifold, making it essential for any high-performance or supercharged engine build. Whether you're upgrading a street vehicle, preparing a track platform, or maintaining existing turbocharged equipment, this inlet flange provides the structural integrity and reliability required for sustained boost delivery.

Manufactured from high-grade steel and finished to exacting tolerances, the T25/T28/GT25 Turbo Inlet Flange features a robust 4-bolt mounting pattern designed for secure, leak-free assembly. The 0.5-inch thickness ensures minimal deflection under boost pressure, preserving seal integrity and preventing turbo-to-intake separation during transient throttle events. The flange's compact footprint—measuring 6 by 7 inches across the mounting face—accommodates tight engine bay configurations while maintaining accessibility for installation and future service work.

Technicians and builders working with T25, T28, or GT25 turbocharger families will benefit from this application-specific component, which eliminates fitment guesswork and ensures proper airflow geometry from compressor to engine. Installation requires standard fasteners and basic hand tools; the flange mates directly to OEM or aftermarket intake manifolds equipped with corresponding 4-bolt receiver ports. At 0.79 pounds, it adds negligible weight while delivering measurable durability gains on turbocharged platforms experiencing frequent boost cycles or elevated manifold pressure.
