Thanks for your honest feedback. The material is stretch nylon knit construction so the air flows through rather easily. The primary purpose is to keep the bumper clean and bug-free. I haven't noticed any affect what-so-ever on the 443 horses. It simply secures to the V with 3 snaps on each side of the wheel well and 3 plastic hooks under the hood in a realtively short amount of time. Best part it is machine or hand washable and it folds compactly for easy in-car storage. I asked a friend of mine to make it for me and he may take it to market if there is enough interest. No overheating issues and no marks on my front end. I take the mask off when not in use. Have used used it for about 1,500 miles.
