Hi,
I tried to make some kind of grill cover for winter comutes to my job (I drive 8 miles to my work). I wanted the diesel engine to warm up a litle bit faster and save/insulate some heet during short stops.
I left one space opened, to let some air cool the turbo's intercooler.
The car is Opel Astra, 1,9 l diesel engine
PS: unfortunately I can not post the images, not enough posts
