17-19 L5P 6.6L Boost Tube Upgrade Kit - Red

This 6.6L Duramax L5P 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 87% 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.
