Banks Power 26005 Boost Tube Upgrade Kit 3.5" Red Powder-Coated Intercooler Pipes

The Banks Power Boost Tube Upgrade Kit delivers massive airflow improvements over factory intercooler piping for 2020-2026 Chevy/GMC 2500/3500 6.6L Duramax L5P applications. Banks massive 3.5 inch boost tubes are the largest on the market, flowing 26-45% more air than stock, resulting in quicker turbo spool, improved throttle response, and more power.

Key Features:

• Full 3.5-inch diameter charge air cooler pipes—largest in the industry
• High-quality aluminized steel construction with mandrel bends for maximum strength and durability
• Smooth mandrel-bent tubes deliver more air while reducing boost pressure loss
• Works with stock Duramax intake components using proprietary high-strength 5-ply silicone hoses
• Billet aluminum cold-side adapters with Venturi-like taper maintain boost pressure and volumetric flow
• CFD-designed billet couplers with double parabolic shape maximize airflow
• Red powder-coated finish
• 50-state compliant (CARB EO D-161-155)

Superior Performance Over Stock: Factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components, while competitors max out at 3.0 inches. Hot side flows 490 CFM @ 12" versus stock 388 CFM; cold side flows 635 CFM @ 12" versus stock 435 CFM. Built from mandrel bent steel, Banks Boost-Tubes will never flex, crack, or dry out like OEM charge air pipes.
