HKS Actuator S13/S14

HKS actuator kit provides rod length adjustment to provide better boost control up to 1.0bar of boost manually. Boost range higher than 1.2bar can be achieved with aide of aftermarket boost controllers to direct signals to the wastegate actuator for higher boost pattern. Adjustment should be done carefully with couple turns at a time. Increases boost from the stock 7psi to 11-12psi.

* Please select the appropriate model of your motor when ordering. When adjusting the rod, please use a pressure pump to test the pressure rating which the waste gate opens and closes to your desirable boost pressure. For people that doesn't have a pressure pump, turn just 2-3 turns at a time and drive the car carefully to see what boost pressure is achieved.
