Product details
On the 2014-2018 BMW 4 Series F32 coupe, Airtech Pro Plus (CBM250-APP) swaps switches and gauges for a digital manifold and a color OLED remote. That remote handles four-corner independent control, so each side of the car can be set on its own. There is no complex wiring to chase through the cabin, which keeps the job focused on routing lines and connecting the kit.
The remote display reports tank pressure and bag pressure at each corner, which helps when you want to check every side. A single Viair 444C can take the car from lowest to maximum height in as little as four seconds. Pro Plus rises in two to five seconds, while Basic and Deluxe take four to seven, so the difference is noticeable when you run the lift.
Each strut carries 36 levels of damping adjustment set with the included knob, and the adjustable lower mounts give fine height control at any pressure. Height holds through pressure-based leveling. The coupe applications exclude xDrive, M-Technik and EDC, and the 3 Series from 2012 to 2018 is also listed. Basic, Deluxe and Executive are separate part numbers, so confirm the management level and fitment with the year/make/model checker.
