BANKS 25991 BOOST TUBE UPGRADE KIT-DRIVER SIDE FOR 07-09 CUMMINS 6.7L 24V

OEM replacement for left side boost tube (Driver/Cold side) with silicone couplers. 40 percent greater flow area compared to stock. Better flowing intercooler tubes results in less boost pressure loss allowing for more air and fuel to be delivered to your engine resulting in maximum horsepower. More density maintained from turbo to intake. These boost tubes are designed for serious horsepower.

Banks cold side Boost-Tube has 40 percent greater flow area than stock tubes. Produced from high-quality aluminized steel, our tubes are mandrel bent for constant diameter. This increases performance by allowing 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 grip to prevent leaks or blown boots. These boost tubes are designed for serious horsepower and are compatible with the stock elbow or new Banks Monster-Ram Gen 2 which will improve airflow, and allow the turbocharger to spool up even fast
