No, cool air intakes DO NOT increase MPG. This is a common misconception. Intakes cool air. Which makes the air more dense , which in turn increases the amount of oxygen. Your truck can sense this and will actually burn MORE fuel. Your horse power will increase, your MPG's will not.
No it is strictly subsonic due to its large air intakes
