Air cleaner Plug?

[mdf]

Does anyone out there know a good substitute for the long nla rubber plug located on the air cleaner intake horn on carburated E9s. Part no. 13711252569. I know I don't actually need it but I would still like to have one. Any suggestions appreciated. ..

My Bavaria needed this plug for its air filter housing. I went to Mcmaster-Carr (www.mcmaster.com) and ordered the nearest size I could find. It's part number 9600K527, $2.13 plus shipping. It's slightly smaller than the hole, and there's a little play, but it does in fact fit and stay in place. Cool, huh?
