corrugated hose btw air cleaner and front panel

[Honolulu]

Does anyone know of an aftermarket source for a correct diameter corrugated hose that runs forward from the air cleaner to the hole in the front panel? I've seen some here and there but never the right diameter. I suppose W&N have it but not worth shipping for a single item.

Did you check with the dealer? They were available a few years back when I needed one.

I try to avoid the dealer when possible.

I should check before blindly posting but it struck me after looking at the white CSL in the shop in Portugal. Seems it's widely/readily available online for as little as $12 and change from getbmwparts.com.

And that's why I try to avoid the dealer, besides those guys have never seen and know nothing of a CS.
