About This Product
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.
Specifications
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.
Why It's Better
BANKS BOOST TUBES FLOW BEST
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.
INDUCTION PERFECTION
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.
GOING THE EXTRA MILE
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.
DO IT RIGHT
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.

L5p boost tubes
"Awesome product fit absolutely perfect 0 issues turbo screams and the boost lights up quick love it!!!"
I’ve used Bank several times always turns out very well
"Naturally, five star stars"
My 2 cents
"Shipping was a bit delayed. Banks did have a banner in this part that said it was in limited supply. I got it 12 days after ordering it. That is what it is. Install guide is a little soft on details. Pull the air filter housing mounting bracket on the passenger side. That makes getting that tube off a lot easier and it’s only a 5 simple bolts to remove. If you’re going to install this outside in near freezing temps, heat that aluminum adapter up with a heat gun or you’ll never get it to go on the bottom of that CAC. Inner fenders are easy to take off with a T15 torx and an 90 degree angle drill, no need to put the truck in the air. Both inner fenders need to come out for an easier install. Pulling the bolt on the fan shroud is not necessary, not sure why that’s in the instructions. Removing the factory hot side tube is a pain. Just cut the flex boot that connects the two sections. Comes right out. Be strategic about your clamp positioning. There is only one angle that you can get a tool on the nuts of some of those clamps. Grease the boots with the supplied tube, which will not be enough. Go get a tube of Sil-glide from NAPA. The reducer on the hot side lower tube on the CAC is a little short on the 3. 5” side. Be careful with clamp placement you have about a 1/4” of extra room for that clamp. Make sure that the bead is on the right side of the clamp and not under it. It’s a bit tricky getting it lined up. You can get on that both of those clamps from the top and like 2’ of extensions. The connection between the two hot side tubes is a little sus, just make sure that those clamps are tight. 25-28 pounds of boost with separate these things in short order. Take a short test drive and get that boost pressure up to test it before you hook it up to the trailer and start pulling hills."
more airflow more power!!!!
"fantastic product, the driver side is definitely harder to install. I was able to install it all without removing the tires or the inner fenders. I did have to pull the fenders back a little bit. there is a huge difference between the stock and these. these tubes are the biggest diameter on the market at 3. 5 for hot and cold side where everyone else's is 3. 5 for cold side and 3. 0 for hot side. 10/10 recommend"
Boost tubes
"Great fit meets great looks and great improvements"
Amazing upgrade for the L5P
"Very good quality, perfect fit"
Worth it!!!
"Definitely worth it! Would recommend taking off the cold air intake bracket that holds the intake box to assure the cold side factory clip is fully full seated around the intercooler flange."
Love em
"They are awesome and as described would be cool to have color options and did have to clean the inside of the tubes out but that should be done regardless before any pipe is installed"
Quality Products from BANKS
"Everything from this company is made with quality materials and is worth the investment. The slight turbo sound increase is a nice benefit. Shipping was fast. The install videos are very helpful. Would highly recommend to others!"
Q&A
