Burger Motorsports 3-port MAC low-frequency boost control solenoid for retrofitting a single-turbo kit to the BMW N54 or N55. Plug-and-play harness connector means no splicing into the factory wiring; it's the correct-frequency solenoid needed for accurate boost control once the factory twin-turbo setup is replaced with a single turbo.

Fitment: BMW N54/N55 3.0L single-turbo-kit builds - E60 535i, E82/E88 135i, E90/E92 335i, Z4 35i, F30 335i, F32/F33/F36 435i, F87 M2 (confirm exact single-turbo kit compatibility at checkout).
