GFB's DV plus design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to "pilot actuation" to ensure better performance on stock or modified engines. Furthermore, these benefits won't cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer's "solutions"), the DV plus keeps what works, and replaces what doesn't. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation.This Part Fits: Year Make Model Submodel 2014-2016 BMW 228i Base 2015-2016 BMW 228i xDrive Base 2013-2018 BMW 320i Base 2013-2018 BMW 320i xDrive Base 2012-2016 BMW 328i Base 2014-2016 BMW 328i GT xDrive Base 2013-2016 BMW 328i xDrive Base 2014-2016 BMW 428i Base 2015-2016 BMW 428i Gran Coupe Base 2014-2016 BMW 428i xDrive Base 2015-2016 BMW 428i xDrive Gran Coupe Base 2012-2016 BMW 528i Base 2012-2016 BMW 528i xDrive Base 2013-2015 BMW X1 sDrive28i 2013-2015 BMW X1 xDrive28i 2015-2017 BMW X3 sDrive28i 2013-2017 BMW X3 xDrive28i 2015-2018 BMW X4 xDrive28i 2012-2016 BMW Z4 sDrive28i
