Banks Boost Tube Upgrade Kit 20-25 GM 6.6L Duramax L5PHave you upgraded your L5P with a cold air intake, maybe a programmer, but looking for some more power and boost? The factory intercooler pipes on each side of your intercooler are a measly 2. 5" diameter and built from a combination of plastic, rubber, and metal, making them highly susceptible to cracking, leaving you stranded on the side of the road. Banks massive 3. 5" boost tubes are the largest on the market, flowing more air than stock. Smooth

Have you upgraded your L5P with a cold air intake, maybe a programmer, but looking for some more power and boost? The factory intercooler pipes on each side of your intercooler are a measly 2.5" diameter and built from a combination of plastic, rubber, and metal, making them highly susceptible to cracking, leaving you stranded on the side of the road. Banks massive 3.5" boost tubes are the largest on the market, flowing 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. 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 unique to the 2020-2024 model, a pair of billet aluminum cold-side adapters. These couplers for the intercooler connection and the throttle body openings, are specially made for the airflow requirements on the L5P and feature a venturi-like taper on their inside diameter maintaining boost pressure and volumetric flow.

INDUCTION PERFECTION
Revised for the 2020-2025 L5P, Banks Power has looked at the new design restrictions and engineered an induction solution to fit it. Even with the new engine bay layout with even tighter fitment under the hood, Banks engineers were still able to maintain a full 3.5" diameter on both the hot and cold side of their boost tubes.

GOING THE EXTRA MILE
With the release of the 2020 L5P platform, GM has revised, moved, and updated several components throughout the engine bay. This includes not only the routing of the charge air pipes, but also material construction and connection mechanisms. Banks' 2020-2024 L5P Boost Tubes now feature a tapered billet coupler and quick connect on both ends of the pipe. No other manufacturer of intercooler pipes use this method of mounting.

Banks engineers used CFD simulations to design the perfect taper and unique double parabolic shape on both ends to maximize airflow and reduce turbulence at the connection points. When you engineer the largest intercooler pipes out there, you have to make sure they connect properly and install easily too.

DO IT RIGHT
For the 2020-2025 L5P, GM decided to go with a near full rubber hose design on the cold side. While this might make assembly easier at the GM plant in Ohio, the flex and swelling this hose provides leaves additional performance on the table. Banks boost tubes will never crack or dry out like the the rubber OEM Charge Air Pipes. Banks Boost Tubes are mandrel bent from aluminized stainless steel and designed to resist deformation from clamping force and other stresses for unparalleled durability and strength.

Quality just isn’t there
Color: 3000K Warm, Size: 2Roll x 16.4ft
Was very excited to receive this product because I had difficulty lighting op these LED strip lights, this looks like a package that had everything that I needed. First off, the strip lights themselves are very thin with wise and would look funny on my project, the adhesive backing did not stick at all once removed The touch sensor works great for about 10 minutes and then completely died, overall not impressed with the quality of this product, sending back

Excellent Cabinet Lights!
Color: 3000K Warm, Size: 1Roll x 16.4ft
Great cabinet lights. Easy to install and connect. The touch less control is handy and works well to dim and turn the lights on and off. Been using them for half a year now. No complaints.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
