i have it on my 2500hd high country, i like it in the winter, helps engine warm up quicker, so you really dont need a engine cover for the winter, when it is come to MPG nothing, worthless on the gas trucks but every gm trucks comes with it standart, a lots of trucks missing shutters but nobody complains about it and no credit paid to the buyers, you just have to pay attantion when you buy anything new .

it is standart on every gm trucks,some people doesnt get it because of shortage and no credit paid to the buyers.

i haves 2020 2500 diesel high country and very happy having the shutters, it is a very useful during the winter, helps engine warm up quicker, i dont think it is worth the have on gas trucks, doesnt do anything with MPG either.

ofcourse diesels has shutters to, it is standart on any gm trucks, because of shortage some people are not lucky to grt what thry already paid for it .
