The 494-HSP is best known as the Max Air Flow Bundle for the 2007.5-2010 LMM Duramax-equipped Chevrolet and GMC trucks. This bundle kit is the way to go if you are looking to get everything that HSP Diesel makes for the LMM to increase and maximize performance.
What is the Max Air Flow Bundle for the LMM?
The Max Air Flow Bundle for the LMM Duramax trucks is a great kit for the person looking to get everything they need all at one time. This kit works great even for those of you who are thinking they will never go away from the factory turbo or injection system because this bundle brings out the maximum performance in those factory systems. The Max Air Flow Bundle will also work well with drop-in style turbochargers and aftermarket injection systems.
Tell us about the Cold Air Intake that comes in the Max Air Flow Bundle
The Cold Air Intake in the Max Air Flow Bundle makes major changes compared to the factory setup. HSP Diesel started by making changes to the size of the intake tube increasing the intake tube to a 4 1/2 Inch design to bring as much air through the tube as possible.
While we saw an increase in the amount of air we could bring in we needed to make sure the intake could actually breathe that amount of air in. So we paired the intake with a high-quality filter and an open design, we used our heat shield box to prevent the hot air from the engine bay from being sucked into the intake. We have seen on an average 20 horsepower and 58 pounds of torque increase on the dyno.
Tell us about the Hot Side Intercooler Tube that comes in the Max Air Flow Bundle
The Hot Side Intercooler Tube is a part that fails not only often but causes major headaches when it does fail. Now what we mean by that is this Hot Side Intercooler Pipe often leaks at the factory lower intercooler boot. HSP Diesel solved this problem by removing the need for that boot and allowing for a straight connection at the intercooler.
HSP Diesel also increased the Intercooler Tube to a 3 Inch mandrel-bent style. This gives a lot more space for air to be packed into that tube and with the mandrel bends, we were able to minimize the turbulence and increase the overall flow up to 40 percent.
Tell us about the Cold Side Tube that comes in the Max Air Flow Bundle
The HSP Diesel Cold Side Tube makes a massive difference when compared to the factory design. The HSP Diesel Cold Side Tube is a 3 Inch diameter mandrel-bent design that increases the flow and reduces the likelihood of failures.
Increasing the performance overall of the entire system. This coldside pipe is made to work with the factory bridge and still increase the airflow!
Tell us about the Billet Thermostat Housing Kit that comes in the Max Air Flow Bundle
The Billet Thermostat Housing Kit in the Max Air Flow Bundle is a great addition to any truck. We designed this kit to not only work better than the factory setup but also look better.
HSP Diesel did this by removing the coolant hose that goes over the driver's side valve cover, this gave much more ample room for engine work and modifications. In addition to moving this, we use a Billet aluminum that is CNC machined to give an even better look and performance.
Tell us about the VGT Intake Mouthpiece that comes in the Max Air Flow Bundle
The VGT Intake Mouthpiece is a part that when inside the Max Air Flow Bundle brings everything together. The VGT Intake Mouthpiece is important because all of this added flow doesn't work if we can't handle the air that comes in through the intake.
The VGT Intake Mouthpiece is hand-assembled and creates a much better seal with the O-Ring style and this prevents unfiltered air from getting into the turbo and creating a boost leak.
Tell us about the Factory Replacement Coolant Tank that comes in the Max Air Flow Bundle
The factory coolant tank in the Duramax engine is prone to not just failure but looking awful. We say this because it is made of plastic and that plastic gets dirty and turns yellow quickly. We also see a common failure point of the factory coolant tank cracking this causes leaks and can quickly turn into a major failure of components.
We solve this problem by making the Factory Replacement Coolant Tanks out of CNC bent and cut aluminum that is then hand-assembled. Using factory provisions and a low coolant sensor this tank is a drop-in design.

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.
