The Banks High-Ram and Boost Tube intake system improves airflow efficiency from the intercooler. This results in greater air density, responsiveness and MPG while providing a significant 64 percent reduction in pressure loss. Includes a 3-1/2 inch constant-diameter Boost Tube to flow air from the intercooler without restriction.
How it works: An intercooler increases air density allowing your engine to produce more power. You don't want to restrict the flow of air exiting the intercooler, unfortunately, that's exactly what the stock piece does. The factory inlet elbow is cramped and angular compared to Banks' larger, streamlined cast-metal High-Ram. Banks' High-Ram intake and boost tubes flow air much more efficiently and provide greater boost without the drawbacks of raising turbine backpressure.
In flow tests, the High-Ram intake delivers up to a 64 percent reduction in pressure loss while improving acceleration and fuel economy!
Note: 2005 Excursion owners must identify which manifold they have.
