What motor/year is your 528? For valance you can either go with a aftermarket diffuser, modify your own, or a neat trick is to buy the M-sport diffuser from the 550. The OEM 550 M-sport diffuser already has the quad outlets cut due to the trapezoids, clips into the m-sport, and comes in bare urethane with a attractive price point of sub $100.00
We offer a system for the 3.0l N52B30 equipped 528i, but for the updated N20 motors inlet pipe modification is required.
