11 Mode valve controler.
Very simpel to install about 5 min, and then u can open the valves up to 100% wen u drive in road mode with the little comander. You can go in website from 11 Mode and look the price and how simpel ist to install.
It works on BMW M2/M3/M4 G87 Models S58 engine. New price was 225 swiss francs.
