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.

So cutie
Color: Cloud White, Material Type: Paper, PU
This is a bit large for a travel size jewelry box lol I really thought it was going to be a bit smaller than what it was. I can see why some of the ladies in the comments are saying they’re using it as their main jewelry box since they don’t have much jewelry for a standard sized jewelry box.
With that being said, it’s cute and CAN be small enough for travel. It fits a lot and I got this one in particular bc I like that it has a bigger lower compartment for larger pieces. It’s a nice quality travel jewelry box. It’ll fit my needs. But if you have a knack for packing small and you value space. I’d say skip on this one or do due diligence to double check the measurements to see if it’s something you’re okay with packing.

CUTE
Color: Cloud White, Material Type: Paper, PU
I absolutely love this jewelry organizer! The 2-layer design gives it plenty of space without being bulky, making it perfect for travel. I was able to neatly store my earrings, necklaces, rings, and bracelets without anything getting tangled.
The interior is soft and protects my jewelry really well, and the compartments are thoughtfully designed to keep everything in place. The compact size fits easily in my suitcase or handbag, which is a huge plus.
The cloud white color looks elegant and makes it feel like a great gift option too. Overall, it’s practical, stylish, and very convenient for keeping jewelry organized on the go. Highly
