HSP 2007.5-2010 Chevrolet / GMC Max Air Flow Bundle

Part Number: 483-HSP

The 483-HSP is best known as the Max Air Flow Bundle for the LMM Duramax-equipped 2007.5-2010 Chevrolet and GMC trucks. Whether you're optimizing factory performance or preparing for future upgrades, this bundle delivers excellent performance and visual appeal.

What Is the Max Air Flow Bundle for the LMM?

This bundle includes nearly everything HSP Diesel offers for the LMM platform, delivering noticeable horsepower and torque increases, cleaner engine bay aesthetics, and improved airflow efficiency.

2" Replacement Passenger Side Up-Pipe

Factory up-pipes are restrictive and prone to failure—especially on the passenger side. HSPs 2" up-pipe uses heavy wall 304 stainless steel tubing for better flow and long-term durability.

Hot Side Intercooler Pipe

The factory pipe is a frequent failure point. HSPs 3" mandrel-bent tube eliminates the lower boot with a direct connection, reducing turbulence and increasing flow by up to 40%.

Cold Air Intake

HSP's Cold Air Intake features a 4.5" mandrel-bent tube and high-flow filter, delivering cooler, cleaner air. Its ideal for performance upgrades and contributes to consistent gains in throttle response.

VGT Intake Mouthpiece

Hand-formed and optimized for airflow, this mouthpiece enhances the intake systems performance. It also supports PCV rerouting and resonator box removal (see part 003-1-HSP for PCV kit).

Cold Side Pipe and Max Flow Bridge

The 3" mandrel-bent cold side tube and two-piece Max Flow Bridge provide improved installation, strength under boost, and superior airflow, completing the charge air system when paired with the hot side tube.
