This 6.6L Duramax LML Banks Boost Tube system is the latest in the Banks Engineering family of high-flow boost tubes. Measuring a constant 3.5" in diameter, Banks hot and cold side tubes have up to 105% greater flow area than stock tubes. 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. This kit is designed to work with the stock intercooler or aftermarket intercoolers with stock inlet and outlet size and location.
Produced from high-quality aluminized steel, Banks boost 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. The powder-coat finish stops before the end of the tubes for better grip ensuring the 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.
