This CNC-machined wastegate inlet flange is designed for external wastegates using a 2-bolt mounting pattern with a 35mm to 38mm valve diameter, such as TiAL 35mm, TiAL 38mm, Deltagate, Turbosmart, and other similar units. Constructed from 3/8" thick 304 stainless steel for exceptional heat resistance and longevity, this flange resists warping even under extreme turbo system temperatures.

The compact footprint makes it ideal for tight engine bay layouts, while the integrated tapped M8 x 1.25 threaded holes eliminate the need for through-bolting, saving time and improving installation clarity. The internal flow path is precision-machined to ensure smooth gas transition with minimal turbulence, supporting consistent boost control and wastegate performance.
