Banks Power 25936 Boost Tube Upgrade Kit for Select 2004-2009 Chevrolet/GMC (6.6L)

Fits select 2004-2009 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 models (6.6L).

Eliminate flow restrictions in your induction system with the Banks Power Boost Tube Upgrade Kit. The stock driver-side tube uses tight bends and a restrictive 2.375-inch diameter that chokes airflow. This Banks upgrade replaces it with a 3-inch constant-diameter, mandrel-bent aluminized steel tube, providing a 60% increase in flow area over the factory part. This increased volume allows the turbocharger to spool up faster and helps maintain boost pressure density between the turbo, intercooler, and intake for maximum horsepower.

Designed for durability under high-boost conditions, the red powder-coat finish stops before the tube ends to provide a superior grip surface for the included 4- and 5-ply heavy-duty silicone couplers. The system is secured with spring-loaded constant tension clamps, which maintain a strong grip during thermal expansion and contraction to prevent leaks or blown boots.
