Introducing the HSP Max Air Flow Bundle for LMM Duramax Trucks

The 494-HSP is popularly known as the Max Air Flow Bundle, specifically designed for the 2007.5-2010 LMM Duramax-equipped Chevrolet and GMC trucks. If you're on the hunt for a comprehensive kit to boost your truck's performance, this bundle from HSP Diesel is just what you need!

What’s Included in the Max Air Flow Bundle?

This bundle is perfect for anyone wanting to upgrade their truck without the hassle of piecing together individual components. Even if you plan to stick with the factory turbo or injection system, this kit maximizes the performance of those systems. Plus, it works seamlessly with drop-in turbochargers and aftermarket injection systems, giving you plenty of flexibility.

Cold Air Intake: A Game Changer

The Cold Air Intake included in the Max Air Flow Bundle makes significant improvements over the factory setup. HSP Diesel has increased the size of the intake tube to a robust 4 1/2 inches, allowing for maximum airflow. To ensure this intake can handle all that air, we paired it with a high-quality filter and an open design, complemented by a heat shield box to keep hot engine bay air at bay. On the dyno, we've seen an impressive average increase of 20 horsepower and 58 pounds of torque.

Hot Side Intercooler Tube: Say Goodbye to Leaks

The Hot Side Intercooler Tube is notorious for leaking at the factory lower intercooler boot, which can lead to frustrating issues. HSP Diesel tackled this by eliminating that boot and creating a direct connection at the intercooler. We’ve also upgraded the tube to a 3-inch mandrel-bent style, allowing for better airflow and reducing turbulence by up to 40%.

Cold Side Tube: Enhanced Flow and Reliability

The HSP Diesel Cold Side Tube is a significant upgrade from the factory design. With a 3-inch diameter mandrel-bent construction, this tube boosts airflow and decreases the chances of failures, enhancing the overall performance of your system while still working perfectly with the factory bridge.

Billet Thermostat Housing Kit: Performance Meets Aesthetics

The Billet Thermostat Housing Kit is a fantastic addition to any truck. We designed it not only to outperform the factory setup but also to look sleek. By relocating the coolant hose that runs over the driver's side valve cover, we’ve created more room for engine modifications. Crafted from CNC machined billet aluminum, this kit enhances both appearance and performance.

VGT Intake Mouthpiece: The Key to Air Handling

The VGT Intake Mouthpiece is crucial for ensuring that all the added airflow is effectively managed. Hand-assembled, it features an O-ring style seal that prevents unfiltered air from entering the turbo, avoiding boost leaks and ensuring optimal performance.

Factory Replacement Coolant Tank: Built to Last

The factory coolant tank in Duramax engines often suffers from wear and tear, turning yellow and cracking over time. HSP Diesel addresses this with our Factory Replacement Coolant Tank, made from CNC-bent and cut aluminum. This drop-in design retains factory provisions, including a low coolant sensor, ensuring durability and a clean look under the hood.
