Boost Solenoid (MAC Valve) XR5 / MK2 RS / Volvo

Having boost control issues? Your factory boost controller may be giving out.

This is an aftermarket option made by the extremely popular MAC Valves INC. We only sell genuine MAC valves - beware of fake copies that are often sold on the internet.

This is a highly reliable 3-port electronic boost control solenoid valve which is controlled directly by the ECU by a PWM (pulse width modulation) to precisely bleed air pressure and regulate boost via the wastegate actuator.

Covered in Techflex braid, protected by a rubber boot and a completely plug and play connection by the 2 pin Bosch style connector.

Vacuum line nipples are preinstalled and sealed using thread sealant to ensure no leaks whilst in operation.

Need a MAC valve bracket? Simply select the option and a billet bracket will be included.
