NEW High Flow Boost Tube Kit for 2020-22 Duramax

Banks High-Flow Boost Tube Upgrade Kit is now available for the 2020-2022 Duramax L5P! The kit boasts the largest tubes in the industry at a full 3.5″, and they’re mandrel bent which means airflow is uninterrupted. Banks Boost Tubes allow for a quicker turbo spool by improving boost pressure retention (increasing air density) between turbo, intercooler, and intake resulting in maximum horsepower. The system works with the stock intake elbow and intercooler and includes billet aluminum cold-side adapters. No longer will Duramax owners worry about the factory plastic couplers breaking over time as they become brittle.
