Banks massive 3.5in boost tubes are the largest charge air cooler pipes on the market, flowing 680 CFM and 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 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 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.
Banks oversized charge air cooler pipes and a unique billet intercooler adapter results in less boost pressure loss from turbo to intake manifold.
With an 87% 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 while reducing engine stress.
At Banks Power, our goal has always been to out-perform stock, our competitors, and even ourselves.
Fitting a full 3.5" charge air cooler pipe through the existing engine bay compartment of your L5P was no easy task, but we did it.
Put side by side with the factory piping, ours could practically eat the stock one whole, all while smoothing out tight bends and improving outflow.
One of the keys to our high performance comes in our unique cold side billet intercooler coupler.
Our engineers used CFD simulations to design the perfect taper to maximize airflow and reduce restriction and drag at the connection point.
The shape and curvature of this coupler is critical to maintaining the pressure efficiency throughout the intercooler system.
Whether you are looking at the cheap OEM plastic intercooler return pipe that's prone to cracking and failure, or the undersized alternatives from the other guys, there really is no comparison.

"The manuals with colored pictures and the videos were extremely helpful! Pay close attention to the orientation of the clamps. I no longer have codes and you can hear the air passing through. I blew out my stock plastic tubes while towing 20k, instant limp mode. Duramax should come stock with these!"
"Feels good getting the plastic cold side tube and lower quality factory boots off my truck. The install was pretty straightforward once I figured out how to get the tubes lined up. The turbo spools up a bit faster and gets the same work done with a little less pressure. No huge gains because I'm still running stock tunes"
"This really made a big difference in turbo spool. I don’t know how much it did on its own because I installed my WcFab 4inch intake horn and WcFab turbo blanket at the same time but after installing those along with the banks boost tubes it made a huge difference in turbo lag and overall boost numbers. The biggest improvement I saw was EGT reduction. With the parts that I’ve labeled plus PPE up-pipes and manifolds on my l5p my egts won’t get over 900-950 Fahrenheit and that’s in tune 5 with very aggressive custom tuning. Prior to all the parts I put on my egts were sitting anywhere from 1,100 to 1,450 depending on engine load and the grade you going up. Anyways they are well worth the money"
"Great customer service and the pipes are awesome i had them powered coated but they are banks definitely worth the money"
"Great product would definitely recommend i have a 2017 2500 gmc sierra hd Duramax 6.6 and it has nothing but banks performance"
"The fitment was not straight in the connections but worked."
"Awesome products and amazing engineering"
"Easy installation. Proper fit"
"I am very happy with my upgrades thus far. Everytime I pop the hood I smile seeing these nice big red tubes knowing my Duramax is breathing better."
"Awesome product fit absolutely perfect 0 issues turbo screams and the boost lights up quick love it!!!"
