The X4's sportier coupe-SUV roofline doesn't change its ride height, so a powered step is just as useful here as on the standard X3, without cluttering the car's sleek side profile.
This X4-specific board extends automatically as soon as a door opens, delivering a stable, textured step, then retracts flush once the door is closed to preserve the coupe-SUV's smooth side lines when parked. The mechanism runs quietly enough that it's barely noticeable from inside the cabin.
Built from weather- and corrosion-resistant materials, the kit is designed to handle daily use through all seasons without losing its finish or alignment. Installation uses the X4's own factory mounting points for a clean, non-permanent fit.
Is the X4 kit the same as the X3's? No, the X4 has a distinct underbody profile, so it uses its own specific kit.
Does it add noticeable wind noise at speed? No, the board retracts fully flush and isn't exposed while driving.
Is professional installation required? Most owners install it themselves with basic tools, though professional installation is always an option.
