All-In-One Performance Kit

Are you searching for a kit that truly has it all? 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 sneaking into your cold air intake. Did you know that for every 1-degree increase in intake air temperature, you could lose up to 3 horsepower? With this setup, you can keep your engine running efficiently!

High Flow Turbo Mouthpiece

One of the standout features of this kit is HSP's high flow turbo mouthpiece. This clever addition allows you to reroute your factory PCV system and remove the factory resonator box, which helps eliminate engine oil buildup in the turbo and intake system. Plus, it includes 3-inch mandrel bent hot side and cold side tubes along with our max flow Y-bridge and turbo mouthpiece.

Durable Piping Solutions

If you own a 2011-2016 Duramax, you might know that the factory hot side intercooler tube is notorious for failure. Its two-piece design, complete with crimped-on boots, often succumbs to heat and pressure, leaving you stranded. The factory cold side isn’t much better, being made of plastic with an unreliable clamping system. This kit replaces all those vulnerable components, featuring race-proven 5-layer silicone boots that promise years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can expect noticeable performance gains while keeping engine temperatures in check.

Efficient Exhaust Management

To help get those exhaust gases out efficiently, this kit includes factory replacement 2-inch up pipes. Our up pipes are built with .120 inch wall tubing and the toughest bellows available, ensuring they last as long as your truck. Plus, we’ve included a factory replacement coolant tank to keep your engine bay looking sharp.

Stylish and Functional Coolant Tank

Our coolant tank boasts an all-aluminum design with a built-in low coolant sensor. To add a splash of color to your engine bay, we’ve also included our upper coolant tube. This tube not only enhances aesthetics but also provides extra space for dual pumps, preventing any hose rubbing against the wheel.
