I am looking at replacing my stock grille with one of the billet grills that is all horizontal slats. The slats come in two sizes 4mm and 8mm. I like the 8mm look but I wonder if that will restrict too much air flow? Anyone have experience with these type of grilles? See links below for details. Thanks!

You should be ok with those.
