New for 2017-19 Chevy/GMC 6.6L Boost Tube Upgrade Kit

Banks Boost Tube Upgrade Kit for the 2017-19 Duramax increases throttle response and reduces turbo lag by utilizing the largest diameter tubing in the industry. Boasting an 87% increase in flow over stock, the 3.5″ full mandrel bent tubes are larger than all competitors and dwarfs the stock 2.5″ crush-bent tubes. The new system works with the stock elbow and intercooler by using proprietary high-strength 5-ply silicone couplers and a unique billet aluminum cold-side adapter to further boost airflow and performance.
