The 05-09 Subaru Legacy GT Blox Racing Manual Boost Controller offers a manual boost controller that rivals its electronic counterparts. Each controller is constructed out of billet aluminum and stainless steel components, and features a boost dial that is easy to adjust yet will not slip causing over boost conditions. Incorporated into the design is a lightweight ceramic ball that is more sensitive and reacts quicker during boost operation. The ceramic ball also contributes to fine and consistent boost pressure adjustments. Also included with the MBC are two additional pressure springs that can be changed for different requirements; a light and heavy duty spring. The light spring is ideal for lower boost requirements and when fine control of boost pressure levels is required. The heavy-duty spring is ideal for high boost pressure requirements.
