[The Hawk]

I just recently got a 2012 X5 35i with 108,000 miles. I’m aware of the possibilities of power you can make on these platform with the N55, but never owned one till now. Reading and watching a lot of videos online about the platform I know they have a tendency of the charge pipe and down pipes breaking, so I plan to replace them both with parts from VRSF. Also the other essentials like water the pump, Vanos solenoid, and oil filter housing filter leaking. Saying all that I was wondering if there’s anything else that I should be looking at to refresh on the car?

Also what else would I need to go stage 2?
