One day DeQ will collect all of his posts and create a How-To book for constructing / rebuilding every part of the E9!
@lens,
i used an oiginal bmw gasket too, and it is nor small, size is correct, as you can see in the pics, for a write-up see here

Having seen multiple RAL codes fly by for te aircleaners of carbed engine's, I tried to check for it myself.
Luckily we have a RAL set and an standardized day-light cabinet in the office
I used the inner surface of my aircleaner as a reference.
There seem to be 2 shades used during the life cycle of the carbed aircleaners, a grey and an olive-green. My colour would definitely be the olive green.
The aircleaner came with my car, but I do not have the knowledge if the aircleaner is the correct one for my May 1973 Auto 3.0.
I'm willing to colour match other parts as well; just send me the part, or a piece of it.)
I first narrowed down the search to ~15 possible matches. Pic 1.
From that I shortlisted 4: RAL#'s, pic 2&3&4.
RAL7022: too grey. I even had a paint spray can in this colour, and it was indeed to brownisch grey. not green enough.
RAL 6015: Best match from the standard 197 RAL color set. I just bought a spray can, will update with a pic when it is painted (first it will be glass bead blasted ).
RAL 6008: Too green
RAL6006: Just a little too light, but a very good second choice.
In a while I will update with pic 5, using RAL 6015.
Hope this helps other in choosing the correct colour.

@ DeQuincey; I have asked my local BMW dealer about the rubber part that seals the lid to the aircleaner. Partnumber acc books is 13 71 1 225 160 “Gummiring”.
The dealer replied yesterday that it is unfortunatly NLA.
Where did you find your part?
Addendum; as i just finished the above university study, my colleague mentioned that there is a second RAL systemwhich also has a more detailed color system, called the 'D2' set with over 1600 colour patches. In that set I found an even better match (possible the same 7 digit number as Dequincey reported on):
RAL 120 03 05 is best fit so far, even better then RAL 6015 mentioned above. Identical to my engineers eye.
RAL 140 30 05 is also a better fit compared to RAL 6015, but slightly off still.
And, just like DeQ probably experienced; these colour codes are used industrially, so I could not find them in a spray can unfortunately.
Ps: note that it is very risky to compare the images on a screen to a part color. Your monitor is likely way off compared to the actual RAL cards. Starting with the fact that google gives 90% of results with different tones. Some of them are close. Even so, most of them are way off compared to a RAL swatch next to my screen.
I did a quick search and this website popped up as being able to supply that paint in an arcrylic enamel at what seems to be a very reasonable price . What is the right sheen (gloss, semi-gloss)? I’m asking because my stock AC was painted a very glossy metallic grey by a PO and I wanted to return it to the correct finish/color.
RAL grey
My search also yielded multiple places in the UK that can supply this code in a spray can, including a 2-part catalyzed formulation (which is preferred for resistance to gas and other solvents like carb cleaner) .
Steve, does your source do catalyzed spray cans?
Jesus, what is the fuzzy ring around the filler cap in the picture of your engine on the 21 Dec 2015 post on this thread, page one?
