Complete Duramax Performance Kit

Are you on the hunt for a comprehensive kit that ticks all the boxes? Look no further! This kit comes equipped with a mandrel bent 4 1/2 inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box that keeps unwanted hot air from entering your cold air intake. Did you know that for every 1-degree increase in intake air temperature, you can lose up to 3 horsepower? With this kit, you can keep those temperatures in check!

Key Features

• High Flow Turbo Mouthpiece: This feature allows you to reroute your factory PCV system while removing the factory resonator box. Say goodbye to unwanted engine oil gumming up your turbo and intake system!
• Robust Tubing: Enjoy 3-inch mandrel bent hot and cold side tubes, complemented by our max flow Y-bridge and turbo mouthpiece for optimal performance.

Upgrade Your Intercooler Tubes

If you own a 2011-2016 Duramax, you might know that the factory hot side intercooler tube is prone to failure. Its two-piece design, complete with crimped-on boots, can easily let you down under heat and pressure. This kit replaces all the failure-prone piping and features our race-proven 5-layer silicone boots, ensuring you have years of worry-free driving. With our max flow Y-bridge and turbo mouthpiece, you can look forward to improved performance while keeping your engine temperatures down.

Exhaust and Coolant Solutions

To help your engine breathe easier, this kit includes factory replacement 2-inch up pipes made from .120 inch wall tubing, featuring the toughest bellows on the market. This ensures they last just as long as your truck. Plus, we’ve included a factory replacement coolant tank that not only keeps your engine bay looking sharp but also features an all-aluminum design with an integrated low coolant sensor.

Stylish and Functional Additions

To top it off, we’ve added an upper coolant tube that brings a pop of color to your engine bay while providing extra room for dual pumps, preventing any hose rub against the wheel.
