Banks massive 3.5" boost tubes are the largest on the market, flowing 26-45% 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 charge air cooler pipes in the industry, measuring in at a full 3.5 inches. Every other competitive product on the market tops out at just 3.0 inches, and your factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components. By contrast, Banks Boost Tubes are made of high-quality aluminized steel for maximum strength and durability. With Banks Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower.
The Boost Tubes work with the stock Duramax intake components by using proprietary high-strength 5-ply silicone hoses. Unique to the 2020+ model, a pair of billet aluminum cold-side adapters are also used for the intercooler connection and the throttle body. These are specially made for the airflow requirements of the L5P and feature a Venturi-like taper on their inside diameter to maintain boost pressure and volumetric flow.
Banks oversized charge air cooler pipes and pair of unique billet adapters results in less boost pressure loss from turbo to intake manifold.
With an 26-45% improvement in airflow, your turbo can spool faster and sustain boost pressure with less wasted energy and heat.
Banks Boost-Tubes allow your engine, and specifically your turbo, to work less hard in compressing intake air; this maximizes horsepower delivery and throttle response while reducing engine stress.
Even with the tighter engine space in the 2020+ L5P, Banks engineers were still able to maintain a full 3.5" diameter on both the hot and cold side of our boost tubes.
Put up side by side with the factory intercooler piping, ours could practically eat the stock one whole!
The combination large smooth mandrel bends and steel construction put the Banks Boost-Tubes in a performance and durability class of their own.
GM revised, moved, and updated several components throughout the engine bay for the 2020+ L5P, including a new coupler system on the cold side.
Our engineers used CFD simulations to design a pair of billet couplers for both ends of the cold side tube with a perfect taper and unique double parabolic shape to maximize airflow and reduce airflow restriction.
The shape and curvature of these couplers are critical to maintaining pressure efficiency throughout the intercooler system.
For the 2020+ L5P, GM decided to go with a near full rubber hose design on the cold side.
While this design might have simplified production for GM, its added flex and hose swelling leaves potential performance on the table.
Built from mandrel bent steel, Banks Boost-Tubes will never flex, crack, or dry out like the OEM Charge Air Pipes. They are built to resist clamping force deformation and other stresses for unparalleled durability and strength.

"Just had a Banks boost tube upgrade kit installed on my 2021 GMC Sierra Denali 2500HD Duramax and the quality of the kit is excellent. Much stronger than the factory tubes and the fitment is perfect. Definitely a solid upgrade"
"I put on the banks boost tubes and turbo inlet just prior to a 3k highway trip. I have a 2020 L5P 3500. The engine had quicker pick up and ran about 100 rpm lower at 70 MPH. Trip to TX from VA. I got about 2 mph increase than before. I went from 21 to 23 mph on average with the best 50 mile at 26. 7. I ordered the cold air intake. Interested to see what that will do."
"Great Upgrade for my 2024 2500. Definitely feels good towing and improved gas mileage so far. I also added the intake and turbo inlet at same time. Traveling on the open road has been better for sure!!"
"Great upgrade to my 2023 GMC 3500HD Denali dually. Sign cast increase in air flow from the factory pipes. Only somewhat negative comment is that delivery took 30 days but I ordered around Christmas on Dec 10th, however, Banks sent out several communications about the holiday delays so that is great customer service."
"Definitely had made a differende in performance! Along with the pedal Monster and Ram Air Intake, Truck is pretty snappy!"
"These have really helped my truck breathe better as a compliment to the Banks intake, intake horn, and exhaust. They also have made my truck feel smoother when driving and increased my MPGs."
"Quality of Product was as expected. You guys could do a better job on the install instructions. It needs to have all the little detail you’ll run into like a “pro tips” section would have. The cold side O rings made it super tight and hard to get on. And the hot side needed a lot of adjusting to get the tubes to work and fit right. Overall I felt like the information available downplayed how hard this actual install was."
"Have not installed yet, still waiting on remaining parts. I have never had to wait for parts for months and months. Need to spend less time on YouTube, and pay more attention to the production process. They must think people have forever and they don’t care about your deadline."
"I would rate these a 5* but it is ridiculous how long it takes before they were shipped, but my card was charged as soon as I order. I am still waiting for my air intake!!"
"Not intalled, yet. I see why this product is on back order. The quality is impeccable. I cannot wait until these are installed."
