TiAL 002943 F38 38mm External Wastegate 2-Bolt Flange

The TiAL F38 is a legendary external wastegate that has been a staple in the performance turbocharger community since its introduction in 2001. Built around a 38mm valve — the same valve diameter used in the TiAL MV-S — the F38 features a classic 2-bolt flange design that has become a widely adopted industry standard for turbo manifold fabrication.

The F38's body stands approximately one inch taller than the MV-S, providing enhanced internal volume and flow characteristics for more precise boost control. Its robust, time-tested construction makes it a go-to choice for turbocharged street, track, and competition builds where reliable boost regulation is critical.

• Time-tested design in continuous production since 2001
• Taller body profile compared to the MV-S for improved internal volume
