It depends on what you're using it for. I'll assume that it's for using an Amsoil bypass filter on. A legit Cummins thread mount is quite expensive (like $90 w/o any hardware - single mount). Various Amsoil mounts are available, the cheapest being the (as was mentioned) BP-80A. It's got small ports, so this would be out if you're JUST looking for a remote to throw a full flow Cummins filter on.
