TiAL 002910 F38 38mm External Wastegate 2-Bolt Flange

The TiAL F38 External Wastegate is TiAL Sport's iconic 2-bolt flange wastegate, first introduced in 2001 and continuously refined into one of the most trusted external wastegates in forced induction. Featuring a 38mm valve diameter, the F38 delivers precise boost control and reliable performance in both street and competition applications.

The F38 shares the same 38mm valve size as the TiAL MV-S wastegate while featuring a taller body design — approximately one inch taller — allowing for improved flow characteristics and packaging flexibility in tight engine bays. Its classic 2-bolt inlet flange is widely supported by aftermarket exhaust manifold manufacturers, making integration straightforward for most turbo builds.

Key Features:

• 38mm valve diameter for high-flow boost regulation
• Classic 2-bolt flange inlet design — widely compatible with aftermarket manifolds
• Proven design in continuous production since 2001
• Taller body design compared to the MV-S for improved flow and fitment options
• Suitable for street performance, road racing, and competition builds
• Available with a range of spring pressures to match boost targets
• TiAL Sport precision manufacturing for long-term durability and consistent actuation

The TiAL F38 is a benchmark external wastegate trusted by tuners and builders worldwide. Whether used in a high-horsepower race build or a spirited street car, it delivers the consistent, repeatable boost control that TiAL Sport is known for.
