2020-2025 Duramax Boost Tube Upgrade Kit (26005)

Fits

With this Banks boost tube Upgrade Kit you are getting the biggest boost tubes on the market at a massive 3.5", producing more airflow over stock! Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss producing a quicker turbo spool and more power. 

These Boost Tubes work with the stock Duramax intake components by using proprietary high-strength 5-ply silicone hoses. Unique to the 2020+ model, a pair of billet aluminum cold-side adapters are also used for the intercooler connection and the throttle body. These are specially made for the airflow requirements of the L5P and feature a Venturi-like taper on their inside diameter to maintain boost pressure and volumetric flow.
