The HSP Cold Air Intake Bundle for LMM Duramax

Introducing the 481-HSP, commonly known as the HSP Cold Air Intake Bundle, designed specifically for the 2007.5-2010 LMM Duramax-equipped Chevrolet and GMC trucks. This bundle is a fantastic upgrade for any LMM Duramax truck enthusiast!

What’s Included in the HSP Cold Air Intake Bundle?

The HSP Cold Air Intake Bundle is a thoughtfully curated kit containing everything you need to maximize your cold air intake setup on your LMM Duramax. With this bundle, you can be confident that you're getting the best performance possible under your hood.

Let’s Talk About the Cold Air Intake

While the LMM engine is impressive right out of the box, many owners find that the stock intake just doesn't cut it. HSP Diesel understands the importance of having an intake that can keep pace with the demands of these powerful engines. That's why we’ve increased the intake tubing size to a robust 4 ½ inches and crafted it with mandrel bends.

This design significantly boosts the amount of air flowing into the engine while minimizing turbulence. Plus, our HSP Diesel heat shield ensures that your intake stays cool by blocking hot air from the engine bay. The result? A steady stream of cooler air with an optimized flow path, allowing you to harness all that power.

What About the VGT Mouthpiece?

The factory mouthpiece on the LMM often leaves much to be desired. Many people upgrade to a high-quality cold air intake like the HSP Diesel version, but neglect to replace the stock mouthpiece. This mismatch can create airflow issues because the stock mouthpiece simply can't handle the increased flow.

That’s where the HSP Diesel VGT Mouthpiece shines! Designed with improved bends and a larger capacity, this mouthpiece is hand-fitted to ensure a perfect match. When paired with our Cold Air Intake, this combo can efficiently move the air your engine craves from the get-go.
