Banks Power 11-16 Chevy/GMC 2500HD/3500HD Diesel 6.6L Boost Tube Upgrade Kit

Banks boost tubes are larger than the factory pipes and designed to work with the stock elbow and intercooler to improve airflow, and allow the turbocharger to spool up faster. Banks hot and cold side tubes have up to 105% percent greater flow area than stock tubes. Produced from high-quality aluminized steel, the tubes are mandrel bent and constant diameter. This allows for quicker turbo spool. Better flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower. Our powder-coat finish stops before the end of the tubes for better grip ensuring our 4- 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.
