Ram air intake?
Many years ago I met a guy who drove a VW EuroVan cargo van for long distance deliveries and the thing that caught my eye was the 4-in ABS pipe sticking out the front into the lower half of the bumper. Maybe I'm not recalling correctly it's been many years but I remember there being an s-curve outside to better position intake air suction to high pressure area. He claimed to average 33 miles per gallon and also claimed it made a big difference. In theory it sounds good but would it work?
