Amazon sells the frost-plug style in various sizes (but isn't listing one yet for the YF), anybody planning on trying one this winter? I had a frost plug style last year and wasnt too happy with it. Car was outside in the wind and I think it overwhelmed the 400w heating element. I think id prefer the recirculating coolant style if I could figure out how to tap it into the system..
Agreed about the 400W comment. That seems way too feeble, especially if the car is outside. At the most, that scenario (400W, outside) probably helps just a bit in terms of cutting down engine wear and making starts easier--which really might be all Hyundai is shooting for. But in terms of having heat right away for the driver in that scenario, probably not.
The only VW-approved accessory I could get for my previous car, a Jetta TDI, was a 250W stick-on oil pan heater. Again, perhaps it helped a tad in terms of engine wear (and my car was garaged), but it seemed almost useless. Eventually an enterprising guy on the TDI forum developed an awesome, factory stock-looking inline coolant heater in 1000W and 750W options that perfectly took the place of a lower radiotor hose. I loved that product and I'll bet he sold a boatload.
(Oops, edited to add that I now see the 400W heater is not a Hyundai product, but aftermarket. Maybe the Hyundai product is more powerful. Anyone know?)
