This is foam you can find in car-audio shops - the exact make/model is GMS-011a 10mm. It has aluminum coating on one side and self-adhesive on the other. The hard part was cleaning the underside of the hood

Have you been monitoring your engine temperature?
Go ahead and try it. I paid the equivalent of 25-30€ for a piece 100x130cm, of which I needed 70x130cm, so I still have some scraps to insulate the firewall or side panels.

I doubt that this will dramatically raise the engine's operating temp, but it should keep the heat in longer when the car is parked, so the engine will be warmer after 1-3 hours.

Insulation also makes using engine preheating worth while. I've checked that DEFA doesn't make a block heater for this engine. I'm still searching for another option, as this car will be used almost daily.
