The 584-3-HSP is best known as the Deluxe Max Air Flow Bundle for the 2015-2016 LML 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 LML to increase and maximize performance.
What is the Deluxe Max Air Flow Bundle for the LML?
The Deluxe Max Air Flow Bundle for the LML 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 Deluxe 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 Deluxe Max Air Flow Bundle
The Cold Air Intake in the Deluxe Max Air Flow Bundle makes major changes compared to the factory setup. HSP Diesel started with 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 Deluxe 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 Max Flow Bridge and Cold Side Tube that comes in the Deluxe Max Air Flow Bundle
The HSP Diesel Max Flow Bridge and Cold Side Tube make a massive difference when compared to the factory design. To start the HSP Diesel Max Flow Bridge is a two-piece design, we did this to make sure that not only would the bridge install easy but it would hold up to boost better because of the O-Ring seal that holds it together. Combined with the Max Flow Bridge is the HSP Diesel Cold Side Tube, this 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.
Tell us about the Upper Coolant Tube that comes in the Deluxe Max Air Flow Bundle
The upper coolant tube that HSP Diesel has put inside this package is a great addition to any truck for not only looks but to take away from any possible failure point. Changing over to a metal upper coolant tube removes the possibility of a cracked rubber piece and with the color options, you have this can set an engine bay apart from the so many others out there.
Tell us about the 2 inchќ Replacement Up-Pipes that come in the Deluxe Max Air Flow Bundle
The 2 inchќ Up-Pipes from HSP Diesel are game-changers when it comes to flow and reliability. Using a heavy wall 304 Stainless steel tubing and sleeved bellows these up-pipes are here to work and stand the test of time. Due to the more open design and better flow, we saw a decrease in EGT inch™s and an increase in spool up.
Tell us about the VGT Intake Mouthpiece that comes in the Deluxe Max Air Flow Bundle
The VGT Intake Mouthpiece is a part that when inside the Deluxe 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 inch™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. Our Intake Mouthpiece gives you the ability to reroute your factory PCV system and remove the factory resonator Box, eliminating unwanted engine oil gumming up the turbo and intake system (PCV re-route sold separately see 003-1-HSP).
Tell us about the Factory Replacement Coolant Tank that comes in the Deluxe 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 low coolant sensor this tank is a drop-in design.

How do people know the VIN code?
Engine code is dictated by the 8th character of the VIN number. The 10th character is the year of the truck.
Special note
This only Fits the 2015-2016 LML engines even though the Vin code is the same. This is due to small changes that were made in the engine bay. Please be sure you are ordering for the correct year truck.
