sounds like you got it dialed in. Remind me again what you used for materials? Did you buy or 3D print? Sorry it’s a long thread to back over.I’ve had the opportunity to try out my plugs a few time since my install and made a few tweaks. At first, it was much better towards the sides, but I noticed a little icing in the center because not enough hot air was hitting the windshield. Rather than remove some of the plugs, I drilled small holes in the plugs that are located under where the driver-side windshield wiper sits so a touch mire hot air can hit the wiper. It seems to be working how Jeep should have designed the vents in the first place. I drove around in record snow yesterday (snow falling at 2” per hour with over 20” in to total), and only had a little icing on the driver’s side, where the wiper hits the end of its reach and deposits the snow. This is to be expected. My wipers never iced over and my view was always clear. Not once did I have to stop and scrape ice off the windshield. Very happy!!
