Product details

OEM replacements for left and right side boost tubes with silicone couplers. With up to 105% greater flow area compared to stock, these better-flowing intercooler tubes result in less boost pressure loss from the turbo to the intake manifold. This results in less work for the turbo, improving engine efficiency and power consistency. Banks hot and cold side Boost-Tubes have up to 105% greater flow area than stock. Produced from high-quality aluminized steel, the tubes are mandrel bent and a constant 3.5 inch diameter 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. Works with stock or aftermarket intercooler with stock inlet and outlet size and location. Key Features: Complete set of left and right side boost tubes with silicone couplers. Huge increase in size and flow over stock (3.5in 2.5in/3.38in). Up to 105% greater flow area compared to stock. Mandrel-bent aluminized steel construction. Constant diameter tubing for the best flow. 4- and 5-ply heavy-duty silicone couplers. Spring-loaded constant tension clamps. Greater cooling capacity. Perfect fit and finish. Lower EGTs Are you running the new bad-ass Banks Monster-Ram for the 6.7L Cummins? Banks boost tubes are larger than the factory pipe and designed to work with the stock elbow or new Banks Monster-Ram (3.5 or 4) which will improve airflow, and allow the turbocharger to spool up faster. Banks cold side tubes have 37% 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 natural finish tubes give you the freedom to paint or powder-coat to your color of choice. The bead-rolled ends allow 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.
