Guys, thanks for the posts but the article I red was not about a snorkel, but about replacing the induction pipes from the standard airbox to the plenum chamber/massflow air meter, with metal and blue silicon rubber piping, so as to remove the air resonators from the original ducting, the upshot was improved engine response and better reving through the range, poss better fuel consumption but I do not know on that one. I could probably do the conversion but am unsure on a couple off minor points, anyway thanks again guys, scuddmann
