Really only for looks
I purchased this because I know that EGR does a good job with "no drill" installations for their window vents and hood shields. Most others want you to apply their 3M tape to your vehicle's finish. Only problem is that on my 2016 JKU, the center plug that accepts a screw is undersized and hence not very stout, whereas the outer two plugs are. Additionally - and to be honest - there is no difference in the number of bugs impacting my windshield after installing this hood shield.
