TiAL 002958 MVS-A 38mm External Wastegate All Springs Air-Cooled

The TiAL MVS-A 38mm External Wastegate is purpose-built for high-performance motorsport applications where water cooling lines are unavailable or impractical. Unlike the standard MVS model, the MVS-A (Air-Cooled) variant eliminates the water cooling ports entirely, making it the ideal choice for racing builds, stripped-down track cars, and engine bays without accessible coolant routing.

Featuring a 38mm valve diameter, this wastegate delivers precise boost pressure control with excellent flow capacity suited for a wide range of turbocharged performance applications. The all-springs kit includes multiple spring rates, allowing tuners to dial in the desired base boost pressure without additional hardware.

Key Features:

• 38mm valve diameter for efficient exhaust gas bypass and accurate boost regulation
• Air-cooled design — no water cooling ports, optimized for motorsport and race-only applications
• All Springs included — multiple spring rates provided to accommodate a range of base boost pressure settings
• High-temperature alloy construction for durability under extreme exhaust heat and sustained boost conditions
• TiAL Sport quality — precision-machined components with tight tolerances for consistent, repeatable boost control
• Compatible with standard TiAL MVS inlet/outlet flange configurations

The TiAL MVS-A is a trusted choice among professional tuners and motorsport teams requiring a compact, reliable external wastegate that performs without compromise in the most demanding conditions.
