That is what it is for, low-RPM. If you're fine without it, don't worry about it.

They are very available in junkyards though. The gasser 190s is a good source, Volkswagen VR6 had them, Audi 5-cyl. turbos had them, not sure of the pipe size and M-B has their own electrical plug, but look around and you'll find a cheap replacement if you're creative.

... or go without, sounds like it's no big sacrifice unless you idle for extended periods picking the kids up at school or something.
