HSP Deluxe No Bridge / Cold Side Bundle Kit for 2015-2016 Chevrolet / GMC

The 594-3-HSP is best known as the Deluxe Max Air Flow Bundle for the 2015-2016 LML Duramax-equipped Chevrolet and GMC trucks.

This bundle kit is the ultimate solution for increasing and maximizing performance while keeping your factory emissions equipment intact.

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

This is a comprehensive kit for those who want everything in one package. Whether youre using the factory turbo/injection system or drop-in aftermarket options, this kit optimizes your setup.

Cold Air Intake

HSP Diesel upgraded the intake tube to a 4.5" design to draw in maximum airflow. Combined with a premium filter and a heat-shield box, it avoids hot engine-bay air. Dyno testing showed average gains of 20 HP and 58 lb-ft of torque.

Upper Coolant Tube

Replacing the stock rubber coolant tube with a metal version adds reliability and a custom aesthetic. Its available in multiple powder coat options to match your build.

Factory Replacement Coolant Tank

Made from CNC bent and cut aluminum, the replacement tank uses factory provisions and sensor placements, eliminating discoloration and leaks while offering a drop-in fit.
