Trumpet Socks

["Jim Hill" <jrhill@chorus.net>]

I'm looking for a product called "trumpet socks" - the removable (foam?) air
filters that fit over the air horns of Weber carburetors.

My car has DCOE40 Webers, and I'd like to use these filters when the car is
not actually ON the race track, in hopes of keeping the larger rocks out of
the engine.

I know they're made--by someone--but I can't seem to find them for sale
anywhere.

Thanks,
