They'll fit. But I'd be careful. Apparently it's not a variable wattage device and just pumps out a steady 40 watts. It doesn't say it's VW on any of the sites that I can see and some of the reviews seem to point to it being a fixed output. So I'm not sure what to tell you, but if it's putting out 40w at all times I'd be damn careful which tank and coil I'm putting on it. I don't think there's any system with 2.4ohm coils that can take that kind of power.
