TiAL 002925 F38 38mm External Wastegate 2-Bolt Flange

The TiAL F38 External Wastegate (MPN: 002925) is TiAL Sport's iconic 38mm external wastegate, first introduced in 2001 and continuously refined as a trusted benchmark in forced induction boost control. Featuring the classic 2-bolt flange design, the F38 offers a proven, leak-free connection that is universally recognized and widely supported by aftermarket exhaust and turbo manifold manufacturers.

The F38 shares its 38mm valve diameter with TiAL's MV-S wastegate, while offering a taller body profile — approximately one inch taller — providing improved flow characteristics and easier installation clearance in tight engine bays. Precision-machined from high-quality stainless steel and aluminum, the F38 is engineered to withstand extreme exhaust temperatures and high-boost pressure environments common in performance and race applications.

Key Features:

• 38mm valve diameter for precise and responsive boost control
• Classic 2-bolt flange for broad manifold and downpipe compatibility
• Taller body design compared to the MV-S for improved flow and fitment flexibility
• High-temperature stainless steel construction for durability in extreme conditions
• Compatible with TiAL's full range of actuator springs for adjustable boost pressure settings
• Time-tested design in continuous production since 2001
• Designed for high-performance street, track, and competition turbo applications

The TiAL F38 is a cornerstone product in the turbocharger performance industry, trusted by professional tuners and enthusiasts worldwide. Whether building a street performance car or an all-out race machine, the F38 delivers reliable, consistent boost control backed by over two decades of proven performance.
