Mine is very much made to fit, rather squeezed in! Took quite a while to get it, the A/C bits, the bonnet stay/strut, and the headlights to live in harmony in the same hole.. cut/shortened the outlet pipe to to the afm and trimmed the underside and also 'massaged' the body under it to get the inlet to clear the high beam.
IIRC the washer bottle is from an e34 with headlight wash? I just removed the headlight bottle. It fits perfectly in the gap between the air filter and the impact sensor for the airbags.
Pics might help you get some ideas
