AC0212.2 Stilo to Imsa Adapter

Do you have a Stilo helmet and use a speedcomm or other IMSA type connection for your radio? This is the adapter for you. Stilo uses the "Euro" connecter, while IMSA / Speedcomm / "road racing" uses the "4C" adapter. Visually they look similar, but they aren't.

This is what you need to make your Stilo comms work with a Speedcomm or other IMSA / 4C connector.
