Exclamation E71 08' N54 (35xi) Recommendations


I'm new to the BMW society, I recently acquired an 08' X6 35xi.. It's come to my attention that the 08' model was the only year BMW used the N54 engine type in the E71 style/frame. That being said, it's been a nightmare for myself trying to find mods for this vehicle! I figured it would be easy since the N54 engine is the most customizable engine BMW makes (one can argue). Thus why I'm hear seeking support!

My current modifications: running MDH Flasher tune (~50hp, 4lbs of boost), KNN high-performance air filter, and a muffler-delete. I've replaced all the spark plugs and ignition coils. I will be walnut blasting the carbon build up next weekend (I'm currently at 76K miles).

I've tried to install the aFe Stage 2 N54 DCI intake system, and it doesn't fit my vehicle (as stated). Apparently, the N54 engine in my vehicle is some-what different than other vehicles.

My questions
Does anyone know of an after market intake system for this vehicle?
Has anyone replaced their charge pipe? If so, what brand? (I'm looking at ER with HKS bov.)
Wheel spacers, BMS doesn't support X5/X6, any recommendations?
Oil catch can, Burger Tuning states their's won't fit, recommendations?
Catless down-pipes, recommendations?

Feedback appreciated. Pictures to come.

Below are pictures of my engine with the intake system removed.
