Red it's funny you ask this, because when I was looking for parts for my F1, most of the adds for lighters were titled Cigar, and not cigarette. I think the diameter is going to be pretty standard on anything made today, as mentioned above, because of axiallary plug in stuff, like cell phone chargers, but the cigarette lighter will work for most cigars unless your lighting some really big diameter ones, but you could always rotate the cigar against the burner to get the whole thing lit!
