This summer i took the engine-cover off because i wanted to hear the engine roar while driving.
Now we all know winter is coming. Is it advisable to put the cover back on the engine to preserve engineheat and protect the ccv-valve against the cold or shall i just leave the cover off and enjoy the v8-music..

what do you guys think?
