3SX Manual Boost Controller 20 PSI - MBC

3SX Manual Boost Controller 0-20 psi

This is a custom made boost controller good for holding up to 20 psi, though many people have used them up to 25 psi without issues. Made with all brass parts and stainless spring and ball, you don't have to worry about rust or corrosion leading to problems from it being installed in the engine bay. This simple install replaces your stock solenoid and will let you run boost up to about 20 psi - we've installed it locally, and the former IPO sold plenty of them.

NOTE: You will NEED an aftermarket boost gauge when installing any boost controller as the stock gauge is not accurate.
