I have heard talk about grill covers to improve FE. Is this an aerodynamic thing, a warm air thing, or both. Most of the ones on this site are the hard plastic. I was wondering about buying one of the quilted winter covers for my Dodge Ram. Would it make an improvement? I was thinking mostly that it would keep the engine and incoming air a little warmer.
