TiAL 002908 F38 38mm External Wastegate 2-Bolt Flange

The TiAL F38 External Wastegate (MPN: 002908) is TiAL Sport's original and enduring 38mm external wastegate, first introduced in 2001 and continuously refined into one of the most trusted boost control solutions in the performance turbocharger industry. Built around a 38mm valve diameter — shared with the MV-S series — the F38 features the classic 2-bolt flange mounting configuration, making it a straightforward, universal fit for custom exhaust and turbo manifold fabrication.

The F38 body stands approximately one inch taller than the MV-S, giving it a distinct profile while retaining the same proven internals and valve geometry. Its robust stainless steel construction and precision-machined components deliver consistent, repeatable boost control across a wide range of boost pressures and operating conditions, making it equally at home on street builds and competition vehicles.

Key Features:

• 38mm valve diameter for efficient exhaust gas bypass and accurate boost regulation
• Classic 2-bolt flange design — widely supported by aftermarket manifold and exhaust fabricators
