Highway specific mods
hey guys I have a (so far) unmodded xA that I only use around the city, never highway. We are about to take a trip from south carolina to new orleans and will be taking the xA. Is there any easy highway specific mods I could do? I would feel good with doing a upper grille block since its not all stop and go like my usual route, how much of the bottom part of the grille can I block off too? Will it really make a difference since its all highway?
