Rubbish! I just drove around all day in 107 degree heat hard top on a/c on at moments with "Zero" temperature change, I would suggest that those having grill insert temp increases have coolant system problems already! So just an ask those big fuck off light bars/spot lights and huge winches sticking out front don't affect air flow in that virgin 7 slot open grill like inserts do? lol Dreaming DarrelFYI...Grill inserts can and do raise coolant and under hood temperatures 20 degrees so if you are in a hot summer day with the ac on can have over temp issues.
