TiAL 006530 Wastegate Actuator Spring for MVS & MVR External Wastegates

The TiAL Sport 006530 is a genuine OEM replacement actuator spring engineered for use with TiAL Sport external wastegates. Designed to deliver precise, repeatable boost pressure control, this spring is a direct fit for TiAL's MVS and MVR wastegate series used in high-performance street and motorsport applications.

Key Features:

• 17-7 PH Stainless Steel construction — maintains consistent spring rate and resists relaxation at temperatures up to 900°F (483°C)
• Precision spring rate — engineered to TiAL's exacting tolerances for accurate, repeatable boost pressure control
• Color-coded identification — TiAL springs are color-coded by pressure rating for easy selection and verification
• Sold individually — springs can be nested in combination to achieve higher target boost pressures
• Genuine TiAL Sport part — manufactured to OEM specifications for direct replacement or pressure-tuning upgrades
• Compatible with TiAL MVS 38mm and MVR 44mm external wastegate assemblies

TiAL wastegate springs set the baseline cracking pressure of the wastegate actuator. Selecting the correct spring rate is essential for proper boost control — the spring pressure determines the minimum boost level the wastegate will hold before opening. Multiple springs can be nested together, with the combined pressure equal to the sum of the individual spring ratings. Always reference TiAL's official spring pressure chart for your specific wastegate model to confirm the correct spring selection for your target boost level.
