Banks Boost Tube Upgrade Kit 17-19 GM 6.6L Duramax L5P 2017-2019 GM 6.6L Duramax L5P

There's definitely something to be said of how cool it looks when you pop the hood of your Duramax and see a massive 3.5" diamater red pipe dropping through the center of your engine bay. But, when you fire it up and the first thing you notice upon take off is how much faster your turbo spools, you'll know that the upgrade was all worth it.

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.
