This replacement actuator utilises the latest piston design to irradicate the failures associated with the OEM diaphragm actuators and is supplied complete with bracket ready to install. This product is built with a predetermined actuator spring suitable for at or slightly above factory boost levels. The actuator can be assembled with a stiffer spring upon request. Please contact us directly concerning this process. While Forge Motorsport is happy to supply you with an actuator capable of holding boost beyond that of your factory unit we are in no way capable of knowing nor suggesting that your vehicle's engine or related systems are capable of supporting or surviving the stresses of such elevated boost pressure. Forge Motorsport nor any of it’s Authorized Distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle.
Diaphragm sealed internals are the default selection for this actuator product but customers now have the option of piston sealed internals. Unique to Forge Motorsport this innovation offers equal performance to the diaphragm type and low maintenance due to the hard wearing nature of piston sealed valve internals
