I have an 1989 F-superduty flatbed with a 7.3 non turbo diesel and i'm looking for some performance upgrades without going to a turbo charger. Does anyone make a cold air intake for this or am i stuck trying to make something up? The truck only has 41,000 original miles on it so i rather buy a unit for it. Any info or links to other sites would be greatly appreciated.
