M54 Sound generator foam (larger piece)

[elfer]

Anyone removing their sound generator foam want to swap the larger piece for a beer token rather than bin it?



I bought my Z4 with both pieces already removed and I want to try it stock for comparison. Vendor still had the smaller piece still but not the larger piece, so I'll need to source that. I can buy a complete new tube for £25 from BMW but, before I do, thought I'd ask on here first in case someone's about to throw their foam out.

Mine was missing when I bought the 3.0si too - I cut up a kitchen sponge and shoved it in to save my ears when the roof was up, it's probably half, maybe two-thirds the size of that picture (I couldn't find a picture of it!) and is maybe right on the edge of being okay with the roof up. With the roof down it howls nicely.

Thanks for the that. I've only driven it roof down so far and agree it's not too loud, it's more that I'm not finding it a very cultured noise. I love the way the M54 sings in my E46 at high rpm and I think I'd rather be hearing that, even if it's not as loud.

I might try that kitchen sponge tip if I can't find the correct foam. Would be nice to try it how BMW intended though.
