BD's X-Flow Power Intake Elbow improves the under hood appearance and performance of your Dodge Cummins engine. Available in a black powder-coated cast aluminum, the X-Flow Power features a larger plenum for increased airflow and smooth radius turns to reduce turbulence and intake pressure losses. Up to three convenient ports (one pre-tapped) make it easy to monitor boost and/or inject water methanol, nitrous oxide or other power adders.
