OEM replacement for left side boost tube (Driver/Cold side) with silicone couplers. 40% 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% 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. Key Features: - Cold Side (Driver Side) Boost-Tube Only - 3.5 inch constant diameter vs Stock 2.73 inch - More density maintained from turbo to intake - Constant diameter tubing for the best flow - Mandrel-bent aluminized steel construction - 4 and 5-ply heavy-duty silicone couplers - 40% greater flow area compared to stock - Spring-loaded constant tension clamps - Increase performance and lower EGTs - Greater cooling capacity - Perfect fit and finish - Combine with Banks Monster-Ram for the most power 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.
