E65 Microfilter ducting reference photos needed

[aureliusmax]

Hi all. Encountering a common issue on my used 7 series and all the wrecked parts car's that I'm seeing and honestly any other no matter the condition. Previous 'mechanics' have had their grubby hands involved and basically anything they touch is always worse off than it was before, none of the parts go back to how they were originally supposed to be installed, I'm finding them either loose hanging in the channel or just some parts or all the ducting parts completely missing off the car
So I'm trying to determine where some of these brackets actually attach because I can't figure it out.

#5 Holder

I believe the E70 has some similar engine bay design as the E65, wondering if anyone would be so kind as to pop open their microfilter area and share a photo how the ducting and brackets are installed. Can't find any info on google images or youtube.

From real oem looks quite different on our e70 but 50i might be quite different on others.

Welp, after some pondering and thinking and feeling around I figured it out. THere's a locating hole on the inside of the sheetmetal that's blind and the conical tab from the lower part of the holder fits into. then it will seat appropriately and pinch over the seam weld. second, the upper most part only friction fits to the cowl above, there's a flat spot formed into the plastic that is mean to contact. on the intake elbow, there's a hole to receive the screw and as you tighten the screw the holder spreads in length to securely fasten the intake elbow. it's a little bit over-engineered but kind of interesting how they did it.
attached some photos. hope this may help the next guy
now it's all back to how it should be. blast the last people going in here and breaking it all !
