external intake duct
talked to a guy with a vW eurovan who had a giant 4" pvc pipe hanging out by front right bumper, right through the fender. i asked him, he said it looks stupid as hell (it did) but he had 500,000 kms on the van and he noticed a 3mpg increase after installing it he said he can regularly get 35mpg on the highway if he drove careful.
i had a snorkle on a truck of mine, it did seem to make a difference. anybody try one yet? i know it is like a ram intake but maybe it was in a higher pressure area on the side
