Webasto is great! In winter time temperature goes really low, sometimes -15 F and imagine how nice its go to a car and just start driving. Ok sometimes i have to remove some frost/ice from windshield but its quite soft after 20 to 30 minutes of heating.
When engine is almost warm it saves gas and engine. Remember that gas cost a bit more here in Finland. Over $4 per gallon!
I didnt install it. I had it done by professionals... All i have to remember is that i must keep gas level upper than 1/4 of tank or webasto wont start.
And yes! Those are headlight washers.
