2013-2018 Cummins Boost Tube Upgrade Kit (25992)

Fits

The Banks hot and cold side tubes have up to 103% greater flow area than stock tubes. Produced from high-quality, 3.5" mandrel-bent aluminized steel, these boost tubes improve airflow, resulting in quicker turbo spool. Better-flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake, resulting in maximum horsepower.

The bead-rolled ends allow for better grip, ensuring the 4-ply and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots. The Raw finish gives you the freedom to paint or powder-coat to your color of choice, or go with the Banks Red for a finished look right out of the gate.
