Front and rear BBK for E92 335i should theoretically bolt right on for 335xi (someone did it with a set of Rotara on a E92)
Front BBK for 330/335i will fit E90 328xi, but the rear needs some parts from the 335 kit.
It's good to know someone is actually taking some initiative to get applications for xi owners!
