Whiper Deflector in Coroplast DIY Fabrication :
Realized the wipers was really in the airflow so I decided to make a coroplast and duct tape whiper deflector to respect airflow near the wipers zone. It took me maybe 2 or 3 hours to build it. I made tests with the deflector but they are lost in the Void. We know that it is a 1.5% gain in MPG (US). Based on a A-B-A-B test. Inconveniant : some leaves and maple scrap get stuck in there.
