Engineered for reliable and consistent boost control, this turbo actuator comes standard with a pre-matched spring for factory or slightly higher boost levels—ideal for stock or lightly modified engines.

For tuned vehicles, stronger springs are available on request to support higher boost targets. Diaphragm-sealed internals provide proven reliability, with an optional piston-sealed design for specific performance needs.

Designed to enhance turbo performance, actual boost remains limited by the engine management system. Compatibility should be confirmed for each application.
