Unlock improved airflow and turbo performance with the Banks Boost Tube Kit for 2020-Current Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks powered by the 6.6L Duramax L5P engine.

Designed to replace the restrictive factory charge-air pipes, the Banks system features massive 3.5-inch mandrel-bent aluminised steel tubing that delivers significantly more airflow while reducing boost pressure loss. The result is faster turbo spool-up, improved throttle response and more efficient power delivery under load.

Unlike the factory plastic and rubber tubing, Banks Boost Tubes are built for long-term durability using heavy-duty steel construction, billet aluminium Venturi couplers and 5-ply silicone hoses. Whether you're towing, touring or simply looking for maximum reliability from your Duramax, this kit is engineered to keep your induction system performing at its best.
