Why does a clutch need to breath? Maybe I'm missing something here, but that is a poor design. I've owned several MT cars and every one of them had an enclosed, completely sealed off transmission. Clutches don't get hot unless you're a terrible driver and ride the piss out of it. Hmm, just doesn't seem like a good design IMO.
