Finish

The 284-HSP is best known as the Deluxe Max Air Flow Bundle for the 2004.5 and 2005 LLY Duramax Chevrolet and GMC trucks. This bundle kit features everything you could need from the HSP Diesel lineup to make more power and get the maximum performance out of your LLY Duramax.


What is the Deluxe Max Air Flow Bundle for the LLY?

The Deluxe Max Air Flow Bundle for the LLY is a complete kit from HSP Diesel. Now what we mean by that is this kit features everything that HSP Diesel makes for the LLY Duramax to take it to the next level in performance and looks. This is the bundle kit that you want if you are looking to do everything you can all at once to maximize your factory setup and drop-in style aftermarket parts.


Tell us about the Billet Forward Facing Thermostat Housing that is in the Deluxe Max Air Flow Bundle

The Billet Forward Facing Thermostat housing that comes with the Deluxe Max Air Flow Bundle is a great piece of the puzzle. What this does is helps reduce the bottleneck that we see in the coolant system from the factory. The stock setup has a cross-over that goes over the driver's side valve cover. This removes that and makes space where necessary, all while giving the engine the ability to cool better.


Tell us about the Hot Side Intercooler Tube that is in the Deluxe Max Air Flow Bundle

The factory Hot Side Intercooler pipe is not the best design. The major issue that is found on the stock application is that the power steering line rubs through the pipe and we also see issues with the boots staying on the pipe. Both of these issues cause boost leaks which cause a loss of power and overall performance. HSP Diesel solves both of these problems by changing the angle the tube goes into the intercooler. We also bumped the diameter of the tube to 3 Inch and that made a difference in the air we can push through to the charge air system.


Tell us about the Replacement Coolant tank that is in the Deluxe Max Air Flow Bundle

The factory coolant tank is very lackluster, to say the least. It also fails often due to cracking in the plastic. So we made this Replacement Coolant tank that is made of metal that is then welded together to fit perfectly in the factory space. The Replacement Tank is also fitted with all the factory provisions and fittings that are needed and features the factory low coolant sensor to prevent any issues with any engine lights.


Tell us about the 2 Inch Replacement Up-Pipes in the Deluxe Max Air Flow Bundle

The factory Up-Pipes are a constant failure point on the Duramax trucks. Our Up-Pipes are made of a heavy wall 304 stainless steel tubing and use heavy-duty sleeved bellows. This is done to prevent the common cracking point of the bellows and warped flanges. We also see an increase in inflow due to the better construction of these Up-Pipes.


Tell us about the Cold Air Intake in the Deluxe Max Air Flow Bundle

The Cold Air Intake that is inside the Deluxe Max Air Flow Bundle is something that you don't want to miss out on. Utilizing a 4 1/2 Inch mandrel-bent tubing you can force the maximum amount of air through that system. With HSP Diesels heat shield box that comes with our, Cold Air Intake will prevent the unwanted hot air from entering the system and keep you with the cool dense air. HSP Diesel has seen on average 20 additional horsepower and 58 pounds of torque. By design, this intake and heat shield box will not draw in air from the headlight bezel and fender port.


Tell us about the VGT Intake Mouthpiece in the Deluxe Max Air Flow Bundle

The VGT Intake Mouthpiece is a crucial component of the Deluxe Max Air Flow Bundle. This piece allows all the air you are drawing in with the Cold Air Intake to actually make its way to the turbo. The factory Intake Mouthpiece is restrictive and just doesn't work like it needs to. With the HSP Diesel VGT Intake Mouthpiece, you will see added power and better spool-up times. The HSP Diesel VGT Intake Mouthpiece will require the use of a PCV reroute.


Tell us about the Max Flow Bridge and Cold Side Tube in the Deluxe Max Air Flow Bundle

The Max Flow Bridge inside the Deluxe Max Air Flow Bundle is upgraded to a 3 Inch diameter to give us the best flow. We also made it a two-piece design to make sure that it was going to perform the best it can and eliminate boost leaks. Our Cold Side Tube was also bumped up to a 3 Inch diameter to flow perfectly with the rest of our pipes and match up just like we want it to with the Max Flow Bridge.
