M57 Pipe kit
Bimmertune pipe kit that fits both 335D and X5D.
15ft of 3.5mm silicone vacuum line is needed if you're doing the turbo related vacuum lines at the same time. If you want to do the engine mount vacuum lines also, you will need 25' of line.
Black is normal vacuum line color, however depending on availability from the manufacturer, blue may be shipped instead. Please let us know if there are any questions/concerns with the color difference.
