The other day I was searching for a glass windshield for my X3, found one but showing up too late for our Thanksgiving trip to the desert. During my search I came across a wind diffuser. I've never seen one and couldn't find any reviews . They claim it helps with wind and dust.So I had a thought. I have a half windshield I wasn't using (didn't like top bend right in sight). I cut 4" and installed. Looks close to same height as the diffuser but with a bend, no vents tho. What do you think ? waste of time or will it work ?
