HSP Cold Air Intake Bundle for LMM Duramax Trucks

Introducing the 481-HSP, better known as the HSP Cold Air Intake Bundle, designed specifically for 2007.5-2010 LMM Duramax-equipped Chevrolet and GMC trucks. If you're looking to give your LMM Duramax truck a boost, this Cold Air Intake Bundle is just what you need!

What is the HSP Cold Air Intake Bundle?

The HSP Cold Air Intake Bundle is a carefully crafted kit that includes everything you need to maximize your cold air intake setup on your LMM Duramax. With this bundle, you can rest easy knowing you're getting the best performance possible under the hood.

About the Cold Air Intake

The LMM engine packs a punch right out of the box, but let’s be honest—the factory intake often falls short. That’s where HSP Diesel steps in. We've designed an intake that meets the demands of your powerful engine. By increasing the intake tubing size to 4 1/2 inches and using mandrel-bent tubing, we've made significant improvements.

This upgrade allows for a larger volume of cooler air to flow in with less turbulence, thanks to our expertly crafted bends. Plus, our HSP Diesel heat shield ensures that hot air from the engine bay doesn’t sneak in. Together, these features mean you can pull in cooler air with a smoother flow, helping you get the most power out of your engine.

About the VGT Mouthpiece

Let’s talk about the VGT Mouthpiece that comes with the HSP Cold Air Intake Bundle. The factory mouthpiece on the LMM is often a weak link. Many folks upgrade to a great cold air intake like ours but forget to replace the stock mouthpiece, which can lead to airflow issues.

That’s why our HSP Diesel VGT Mouthpiece is designed with improved bends and a larger capacity, hand-fitted to ensure the best possible fit. When paired with our Cold Air Intake, this combo delivers the airflow your engine craves right from the start.
