I've always wanted to use them because we get alot of gravel dumped on the roads during the winters and have already found small pebbles lodged between the fins of the radiator. Also, my car has a relatively hug gap in the lower bumper area and it's big enough for a good sized rock to pass through. I'd hate to think what could happen enxt if one of those fly through the gap.
But my main concern with grille inserts is that they may restrict the air flow to the radiator too much, thus increasing the temperature in the cooling system.
I'm looking at Cloud Rider grille inserts with the mesh type. The size of the holes can be viewed here,

What do you guys think? Are those holes too small and just might affect the cooling system operating temp? Thanks for your time and courtesy.
