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.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love.
I can’t wait to read the next one and to complete the series.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot.
Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable.
The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold.
The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.
