What is the Max Air Flow Bundle for the L5P?
The L5P Duramax Max Air Flow Bundle is a kit that gives you exactly what you need. What we mean by this is this bundle is nothing more than exactly what we would recommend for someone that wants to get the most out of their truck but also know that you are keeping it reliable. This bundle currently gives you all the L5P parts that HSP Diesel makes at a discounted price!
Tell us about the Cold Air Intake that comes in the L5P Duramax Max Air Flow Bundle
The HSP Diesel L5P intake is a major change from the factory parts. To start we used a full metal assembly. A large heatshield that takes allows for use of the ram air hood scoop that comes factory on these trucks.
HSP Diesel also uses a metal mandrel-bent intake tube that uses smooth bends to create a radius that reduces the turbulence and increases the flow into the engine.
This means more air that flows faster through the intake and gives the engine and turbocharger the air it is demanding. With no change in tuning, we have seen increases up to 20HP on average.
Tell us about the Hot Side Intercooler Tube that comes in the L5P Duramax Max Air Flow Bundle
The HSP Diesel Hot Side Tube for the 2017-2019 L5P is made from aluminized steel. This gave us a lot more strength but also allowed us to make mandrel bends. The mandrel bends give us the strongest and best shapes to our bends to allow for the best flow and least amount of turbulence.
The HSP Diesel Hot Side Tube for the 2017-2019 L5P is the easiest to install hot side tube on the market today. HSP Diesel upgrades the boots to a 5-ply, high-strength, silicone style to replace the weak and prone-to-fail factory boots. This means you will be on the road longer and with a more reliable platform.
Tell us about the Cold Side Intercooler Tube that comes in the L5P Duramax Max Air Flow Bundle
The factory Cold Side on the L5p is a two-piece plastic design. This is not only weak but because of that design, you have multiple failure points. The HSP Diesel L5P Cold SidePipe is made out of mandrel-bent aluminum and uses a metal adaptor and high-strength silicone boots to install.
This removes those possible failure points and keeps you on the road. The HSP Diesel L5p Cold Side Tube is made to be installed with all of the factory components.

Our Warranty
HSP No BS Limited Lifetime Warranty
At HSP we believe in our products and we stand firmly behind every single one that leaves our facility. For years we have taken care of almost everything and anything that our customers had issues with, but we didn't have a set in stone warranty. We have always gone above and beyond for our customers which set us apart from the rest. We will continue that same standard, but now we are taking things to the next level.
questions we get about hsp diesel daily:
Who is HSP Diesel and what makes their products different?
HSP Diesel builds high-flow, made-in-the-USA diesel performance hard parts that solve real-world airflow restrictions. Their components are CAD-designed, flow-tested, and engineered for durability, clean fitment, and consistent performance. Customers choose HSP because the quality, welds, powder coat options, and fitment are more refined than generic diesel aftermarket parts.
Are HSP Diesel products compatible with my truck?
Most HSP Diesel components are designed for GM Duramax platforms (LB7, LLY, LBZ, LMM, LML, L5P). Each product page lists exact year and engine compatibility. If you're not sure which Duramax engine you have, send us your VIN and we’ll gladly confirm fitment before you order.
Do HSP Diesel parts improve performance?
Yes. Upgrades like intercooler pipes, Y-bridges, turbo inlet kits, and intakes dramatically reduce airflow restriction. Most owners see faster spool, cooler EGTs, smoother towing performance, and better throttle response—even on otherwise stock trucks.
Do I need tuning after installing HSP Diesel parts?
Most HSP airflow parts (intakes, charge pipes, Y-bridges, turbo mouthpieces) do not require tuning to install or drive. However, a tune may help the truck take full advantage of the increased airflow. If a part requires tuning—such as a turbo upgrade—the product page will clearly note it.
Are HSP Diesel parts emissions compliant?
Many HSP Diesel components work with factory emissions systems in place. Some turbo-related or race-use parts may not be emissions compliant. Always read the emissions note on the product page and follow local laws before installation.
How long does it take for HSP Diesel parts to ship?
Most HSP parts are built and powder-coated after you order. Standard colors ship sooner, while custom colors may require 2–4+ weeks depending on workload. Lead times are shown on each product page and updated frequently.
What powder coat colors are available?
HSP offers a wide range of standard colors (black, red, white, blue, etc.) plus custom powder coat finishes. Custom colors may add cost and lead time. If you're trying to match an existing part, send us a photo and we can help you choose the closest match.
Do HSP Diesel kits come with everything needed for installation?
Most HSP parts include the clamps, boots, brackets, and hardware required for a clean install. Larger systems—like turbo kits or intercooler upgrades—may require additional supporting parts. Each product page lists everything included in the kit.
Are HSP Diesel parts compatible with other aftermarket brands?
In most cases, yes. As long as the parts use compatible diameters and mounting points, HSP Diesel components integrate well with other brands of turbos, intakes, intercooler systems, and fueling components. If you already have mods installed, tell us what’s on the truck and we’ll check compatibility.
Will HSP Diesel parts help with towing?
Absolutely. Improved airflow reduces EGTs, increases turbo response, and helps the truck pull more consistently under load. Many daily drivers and towing-focused Duramax owners upgrade to HSP specifically for cooling and drivability gains.
What warranty do HSP Diesel products include?
HSP Diesel provides a warranty against workmanship and material defects. If a part arrives damaged or defective, contact us with photos and your order number and we’ll assist in getting it corrected.
Can I install HSP Diesel parts myself?
Many components—like charge pipes, intakes, and coolant tanks—are DIY-friendly. More complex installs (Y-bridges, turbo kits, or tight-tolerance piping) may require professional installation. Review the instructions to make sure you're comfortable with the job.
