About This Product

OEM replacements for left and right side boost tubes with silicone couplers. Up to 105% greater flow area compared to stock. Better flowing intercooler tubes result in less boost pressure loss allowing for more air and fuel to be delivered to your engine resulting in maximum horsepower. These boost tubes are designed for serious horsepower.
Fitment Note
Not compatible with 2011 Duramax with Active Brake Control/Trail BrakeActive Brake Control Sensor Location

This kit is designed to work with the stock intercooler or aftermarket intercooler with stock inlet and outlet size and location.
Specifications

Banks boost tubes are larger than the factory pipes and designed to work with the stock elbow and intercooler to improve airflow, and allow the turbocharger to spool up faster.

Banks' hot and cold side tubes have up to 105% percent greater flow area than stock tubes. Produced from high-quality aluminized steel, the tubes are mandrel bent and constant diameter. This allows for a quicker turbo spool. Better flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower. Our powder-coat finish stops before the end of the tubes for better grip ensuring our 4- and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots.

Reviews

What A Difference!

"Recently upgraded to the Banks Power intercooler tubes on my 2014 Chevy Duramax, and I couldn't be more impressed. The build quality is immediately apparent, with custom-machined cast end tanks and mandrel-bent boost tubes that really show off the engineering. Since installing them, I've noticed a significant improvement in throttle response and a reduction in turbo lag. The engine feels more responsive across the power band, and my exhaust gas temperatures are running cooler, especially when towing. It's a noticeable upgrade that balances performance and reliability perfectly. Highly recommended for any Duramax owner. ""

Love them

"I recently did the boost tube upgrade kit from Banks and at the same time a downpipe upgrade. I am really impressed. Much better turbo spin up and upped my mpg too! Now I wish I could afford Banks Intercooler upgrade! Maybe in a year or two…"

— Paul C. (4/5)

Solid product

"Definitely way bigger than stock tubes, a lot cleaner looking and paired with there ram air intake its mad a huge difference in how my truck responds"

— Scott R. (5/5)

A must need upgrade.

"I recently purchased these boost tubes after I experienced the hot side blow off from the stock tubes on my 2015 3500 Durmax. If you haven't experienced this, it is just a matter of time. I the Banks upgrade tubes on and they are game changer. My accelration is better and I have noticed an increase in fuel mileage. I have not towed my 35 ft camper yet, but I can already tell it is going to make a difference. I installed the kit myself in my garage using jack stands and it was relatively easy. However I did have to work a little on the hotside inner cooler boot to get it seated correctly."

— Darren H. (5/5)

Installation woes

"Recently purchased the boost tube kit for my 2012 GMC Sierra 2500HD Duramax. I reviewed the installation instructions on line and thought about printing it out. However, since it came with printed instructions, I made the conclusion that those instructions would be the most accurate. Wrong. The instructions supplied with the parts instructed to put the new driver side tube in the same location as the original. The original tube came out the top. Per instructions. The new tube could only be inserted from the top in the wrong orientation. Trying to install it (in what I finally determined was the right orientation) was impossible. The hood was in the way. The instructions did not specify to install from top or bottom. Just the same opening. So after several hours removing and rerouting various wires and components, battery , ecm, bending power steering lines, etc. I finally tried from the bottom. Of course with the wrong orientation, it would not fit either. Finally flipping it to the correct orientation it fit easily. From the bottom. Which the online version of the instructions said to do. But not the printed one. Several hours lost trying to install it with the wrong orientation, dismantling items that didn’t need to be, I finally finished the install. Yes, I could immediately feel the difference, I’m happy with the performance. However if the correct instructions been supplied with the product (various silicone tube part numbers didn’t match the instructions as well), and a simple sticker on the driver’s side tube indicating which end connected to the turbo, which end to the inter cooler, would have saved me several hours of frustration. So happy. Not happy."

— Dave S. (4/5)

Easy install

"I was able to do the passenger side without removing the wheel and wheel well. The Banks people could teach other industries how to make/produce instructions. Very simple to follow. The pipes fit perfectly and do not rub anywhere. No more hot side boost hose popping off. Well don Banks Performance."

— Paul S. (5/5)

awsome stuff

"the power difference between stock and these amazing kit was ok had to take a lot off the truck to get them in but that's ok for upgrades and the power coat finish was great love the look of them"

— jeremy g. (5/5)

2015 LML install.

"Beautiful parts and pieces. However, install video makes it look much easier to install than it is. Found it very difficult to get pipes to plug into the boots. After first sight is inserted. Gonna need lots of muscle and a second pair of hands to help. Otherwise Good quality materials."

— Darin H. (5/5)
