Not something I have on mine - and we're only a couple of years out. Also, not something I've heard of before? I'd be interested to learn more. Where does the hot air go? I've had old cars with the movable air intake that can be used to gather warm air from the exhaust in winter, but nothing with a pump.

There's usually a large supply of cool air around the engine when moving - although obviously more temperate climate in the UK. However, did not have any issues when we had our really hot days last summer (over 38 degrees C) and I was using the Mog for the commute.
