TiAL 002318 Wastegate Actuator Spring Performance Boost Control

The TiAL 002318 is a replacement and upgrade wastegate spring designed for use with TiAL wastegate assemblies. TiAL Sport is one of the most respected names in turbocharger management, and their precision-engineered springs allow tuners and performance enthusiasts to precisely dial in boost pressure targets on turbocharged applications.

Wastegate springs play a critical role in boost control — the spring rate determines the baseline cracking pressure at which the wastegate valve begins to open, bleeding off exhaust gases and regulating turbo boost. Selecting the correct spring is essential for achieving accurate and consistent boost levels.

Key Features:

• OEM TiAL replacement/upgrade wastegate spring

• Compatible with TiAL MVS and MVR wastegate series
• High-quality spring steel construction for durability under extreme heat and pressure cycles
• Direct-fit replacement — no modification required
