I scored some free stainless steel mesh today at a local steel shop. I put some under the bumper as lower grill since there i s a big gap there btw bumper and lower airdam skirt. I don't want any more suicidal bird diving into radiator. I also mouted my new oil cooler yesterday. And the rest of mesh, I put it behind the top grill. I look pretty cool, also functional. No more diving birds and cleaning the radiator : )
