Forge Motorsport Upgraded Piston Design Actuator
The Forge Motorsport Upgraded Piston Design Actuator is a high-quality replacement component designed to enhance the performance of your vehicle. This actuator is specifically built to replace the original component and is guaranteed for life, ensuring long-lasting durability and reliability.
Featuring a predetermined actuator spring suitable for factory boost levels, this product can also be assembled with a stiffer spring upon request. Please note that compatibility with all applications cannot be guaranteed, and the ability to increase boost output beyond the parameters set by the engine-management-system of your vehicle may vary.
With diaphragm sealed internals as the default selection, this actuator also offers the option of piston sealed internals. This innovative feature, unique to Forge Motorsport, provides equal performance to the diaphragm type and requires low maintenance due to the hard-wearing nature of piston sealed valve internals.
The Forge Motorsport Upgraded Piston Design Actuator comes with the necessary mounting bracket for easy installation. It is built with a Green coded spring as standard, but if you require the FMPACTUN spring tuning kit, you will need to select the Piston Type option.
Fitting of this actuator is available at our performance workshop at Progressive Parts. Upgrade your vehicle’s performance with the Forge Motorsport Upgraded Piston Design Actuator today!
