I will be getting a new 325xi in about two weeks, and I'm wondering how many miles the break in should be. I have heard anything between 1000-1500 miles, while not exceeding 3500 rpm and not doing over 55mph. What do you guys think? Also Im going to be in the market for an intake, but i have heard that some of them don't work with bimmers that have xenon lights? Any ideas for a good intake are welcome!
