TiAL 005121 Wastegate Actuator Spring

The TiAL 005121 is a precision-engineered wastegate spring designed for use with TiAL wastegate assemblies. TiAL Sport is a globally recognized manufacturer of high-performance turbocharger components, and their wastegate springs are manufactured to exacting tolerances to ensure consistent boost pressure control and long service life under demanding conditions.

Wastegate springs play a critical role in regulating boost pressure by controlling the point at which the wastegate valve opens. Replacing or upgrading to the correct spring rating allows tuners and enthusiasts to fine-tune boost threshold and overall turbocharger performance to suit specific engine builds and power targets.

Key Features:

• Genuine TiAL Sport OEM replacement/upgrade spring
• Engineered for precise boost pressure actuation
• High-quality steel construction for durability under elevated heat and pressure
• Direct fit for compatible TiAL wastegate housings
• Allows tuning of boost pressure setpoint when combined with appropriate spring rates

Always verify the spring pressure rating matches your target boost level and turbo system requirements before installation. TiAL wastegate springs are available in multiple pressure ratings — confirm part number 005121 corresponds to your desired boost specification.
