Banks Boost Tube Upgrade Kit (Set) for 2017-2019 GM 6.6L L5P Duramax
Increases throttle response and reduces turbo lag
Banks massive 3.5" boost tubes are the largest on the market, flowing 87% more air than stock! Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss resulting in quicker turbo spool and more power.
Banks Boost Tubes are the largest tube in the industry at a full mandrel bent 3.5" compared to competitors’ 3” and the stock 2.5" crush-bent tubes. Made of high-quality aluminized steel, Banks Boost Tubes allow for a quicker turbo spool by improving boost pressure retention (increasing air density) between turbo, intercooler, and intake resulting in maximum horsepower.
The Banks Tube Upgrade Kit works with the stock Duramax intake elbow and intercooler by using proprietary high-strength 5-ply silicone couplers and a unique billet aluminum cold-side adapter to further boost airflow.
