I just don't like the look of plastic engine covers. Never have. Pulled it off my previous car as soon as I got it home lol. Is there any negative to taking it off and leaving it off? I just ask because it has a lot of matting of some sort on the underside. Is that heat shielding, sound deadening, fire retardant, or what? I'd like to just leave the cover off, but not if it actually serves a purpose on these cars.
