BMW B58, S58 Plug-n-play MAC Boost controller solenoid

Visconti Tuning Plug-n-Play Boost Control Solenoid – B48 / B58 / S58

Building a big-power single turbo setup? Here’s the 3-Port MAC Valve Boost Controller for precise boost control, ideal for BMW B48, B58 and S58 engines running an upgraded turbocharger with an external wastegate.

The 3-port MAC solenoid provides precise control of the external wastegate and is particularly well suited for high-power turbo and Stage 3 setups. The Plug & Play wiring harness is designed to connect directly to MOTIV ReFlex or CANBOXPRO controllers.

The wiring harness features a full-length anti-chafing sleeve for improved durability, while the extended wiring allows the valve to be mounted in several different locations within the engine bay.

The kit includes custom Visconti Tuning fittings featuring an extended design that allows the T-fittings to sit securely and deeper inside the vacuum/boost lines. The fittings also leave enough space for securing the hose with a zip tie without damaging the line. The fitting threads have been designed to provide a clean, flush and professional appearance once installed.
