Ford Focus RS MK1 Forge Motorsport Performance Alloy Adjustable Actuator

Brand New Genuine Forge Motorsport Parts & Accessories

This actuator is designed for the Ford Focus RS or STi models

Please note: There are two types of actuator available for this vehicle, either with a straight rod or a bent rod. The two versions are not interchangeable. For this reason, prior to ordering, you should ascertain which version you require. When ordering please let us know which one you need.

The actuator is supplied with no replacement bracket, you will need to reuse your original factory bracket to fit the Forge actuator.

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.
It is designed and built with the intention of increasing the boost output of a turbocharged system. We cannot guarantee compatibility with all applications, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine-management-system of the given vehicle at the time of installation, whether that system is factory or aftermarket.

Please Note:

The pressure figures listed are minimum regulated pressure figures. If you are unsure please don’t hesitate to contact us.

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

Forge Motorsport nor any of it’s authorised distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of allowing for the desired level of adjustment. 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.
