Air Intake Tubing
Material desired depends on the length of run. I did a custom intake system for a motor home engine a few years back I found some bellows type hose connectors from an auto supply that had some neat stuff. I also used a 4 inch aluminum sprinkler pipe el and a straight run of aluminum pipe. If you have to use flex hose you might want to look at the hose that they use to transfer fuel from fuel trucks to underground fuel tanks. No kinking and no collapse with those intake parts.
