Introducing the Deluxe Max Air Flow Bundle

The 584-3-HSP is your go-to solution for maximizing performance in your 2015-2016 LML Duramax-equipped Chevrolet and GMC trucks. Known as the Deluxe Max Air Flow Bundle, this kit is perfect for anyone looking to enhance their truck's capabilities with everything HSP Diesel has to offer for the LML.

What’s Included in the Deluxe Max Air Flow Bundle?

This comprehensive kit is ideal for those who want to upgrade all at once. Even if you're planning to stick with the factory turbo or injection system, this bundle helps you get the most out of those components. Plus, it’s compatible with drop-in turbochargers and aftermarket injection systems, making it a versatile choice for any truck enthusiast.

Cold Air Intake: A Major Upgrade

The Cold Air Intake included in this bundle represents a significant improvement over the factory setup. HSP Diesel has increased the intake tube size to a robust 4.5 inches, allowing for maximum airflow. To ensure this intake can handle the increased air volume, we paired it with a high-quality filter and an open design, complemented by a heat shield box that keeps hot air from the engine bay at bay. On average, users have reported a gain of 20 horsepower and 58 pounds of torque on the dyno!

Hot Side Intercooler Tube: Say Goodbye to Leaks

The Hot Side Intercooler Tube is a common failure point that can cause significant headaches. Many factory setups leak at the lower intercooler boot, but HSP Diesel has addressed this issue by eliminating the need for that boot entirely. Instead, we’ve designed a straight connection at the intercooler and increased the tube size to a 3-inch mandrel-bent style, enhancing airflow by up to 40% and minimizing turbulence.

Max Flow Bridge and Cold Side Tube: Performance Meets Reliability

Our Max Flow Bridge and Cold Side Tube are game-changers compared to factory designs. The two-piece bridge ensures easy installation and durability, thanks to its O-Ring seal. The Cold Side Tube, also 3 inches in diameter and mandrel-bent, boosts airflow and reduces the risk of failures, enhancing the overall performance of your system.

Upper Coolant Tube: A Smart Upgrade

The upper coolant tube in this bundle is not just a stylish addition; it also eliminates potential failure points. Switching to a metal upper coolant tube reduces the risk of cracks that can occur with rubber pieces. Plus, with various color options available, you can make your engine bay stand out!

2 Inch Replacement Up-Pipes: Built to Last

The 2-inch up-pipes from HSP Diesel are designed with heavy-wall 304 stainless steel tubing and sleeved bellows for unmatched reliability. Their open design improves flow, resulting in lower EGTs and quicker spool-up times.

VGT Intake Mouthpiece: The Finishing Touch

The VGT Intake Mouthpiece ties everything together in the Deluxe Max Air Flow Bundle. It ensures that all the added airflow is effectively utilized. Hand-assembled for a perfect seal, this mouthpiece prevents unfiltered air from entering the turbo and creating boost leaks. It also allows for rerouting your factory PCV system, helping to keep your turbo and intake clean (PCV re-route sold separately).

Factory Replacement Coolant Tank: A Durable Solution

The factory coolant tank in Duramax engines is prone to cracking and discoloration. Our replacement tank is made from CNC-bent aluminum, eliminating these issues while providing a sleek look. It’s designed to drop right in, utilizing factory provisions and a low coolant sensor.
