HSP 2013-2014 Chevrolet / GMC Deluxe Max Air Flow Bundle

Part Number: 584-2-HSP

The 584-2-HSP is best known as the Deluxe Max Air Flow Bundle for the 2013-2014 LML Duramax-equipped Chevrolet and GMC trucks. This bundle includes everything HSP Diesel offers to enhance and maximize performance on your LML.

What Is the Deluxe Max Air Flow Bundle for the LML?

This kit is ideal for anyone looking to complete their airflow and cooling system upgrades in one go. Whether you plan to keep your factory turbo and injection or use drop-in upgrades, this bundle is built to optimize factory systems and support future performance mods.

Cold Air Intake

The intake system features a 4.5" mandrel-bent tube paired with a high-flow filter and an open heat-shield box. Designed to block hot engine air while maximizing airflow, it delivers dyno-tested gains of 20 horsepower and 58 lb-ft of torque.

Hot Side Intercooler Tube

Factory pipes often leak at the lower intercooler boot. HSP fixes this with a straight connection and a 3" mandrel-bent design, reducing turbulence and increasing flow by up to 40%.

Max Flow Bridge and Cold Side Tube

HSPs two-piece Max Flow Bridge installs easily and uses an O-ring seal for superior boost control. The paired 3" mandrel-bent cold side tube improves reliability and increases airflow through the system.

Upper Coolant Tube

A durable metal replacement for the stock rubber tube. Improves reliability and enhances engine bay aesthetics with your choice of powder coat finish.

2" Replacement Up-Pipes

Constructed from heavy wall 304 stainless steel with sleeved bellows. Improves exhaust flow, reduces EGTs, and supports better turbo spool-up.

VGT Intake Mouthpiece

This hand-assembled component provides a better seal via O-ring design, eliminating unfiltered air entry and potential boost leaks. It ensures your turbo receives the airflow gains from the intake system.

Factory Replacement Coolant Tank

Replaces the OEM plastic tank prone to discoloration and cracking. Made from CNC-cut and bent aluminum, hand-assembled, and includes all factory provisions including the low coolant sensor.
