Banks 26005 Boost Tube Upgrade Kit 2020-2026 6.6L L5P Duramax

Upgrade the restrictive factory charge-air piping on your 2020–2026 Chevy/GMC 6.6L L5P Duramax with the Banks 26005 Boost Tube Upgrade Kit.

Banks uses full 3.5-inch hot and cold side boost tubes to dramatically increase airflow over the factory 2.5-inch piping. According to Banks testing, the hot side flows 26% more air than stock while the cold side flows approximately 45% more, helping reduce boost pressure loss, improve throttle response, and allow the turbocharger to spool faster.

Billet aluminum Venturi-style adapters, mandrel-bent aluminized steel tubing, heavy-duty 5-ply silicone couplers, and constant-tension clamps provide a strong, high-flow replacement for the factory charge-air system.

The Banks kit provides an upgraded replacement for the factory charge-air system, including applications using GM intercooler charge pipe part number 84914123.
