Everything You Need in One Kit!

Are you on the hunt for a comprehensive kit that truly has it all? Look no further! This kit features a mandrel bent 4 1/2 inch intake tube designed for impressive airflow gains. Plus, with HSP's signature heat shield box, you can say goodbye to unwanted hot air sneaking into your cold air intake. Did you know that for every 1-degree increase in intake air temperature, your vehicle can lose up to 3 horsepower? Keeping that air cool is essential!

High Flow Turbo Mouthpiece

One of the standout features of this kit is HSP's high flow turbo mouthpiece. This innovative component allows you to reroute your factory PCV system while removing the factory resonator box. This means less engine oil gumming up your turbo and intake system—what a relief!

Durable Design for Long-lasting Performance

Equipped with 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, you can expect a significant boost in performance while keeping those engine temperatures in check. Let’s talk about the factory hot side intercooler tube on your 2011-2016 Duramax—it’s notorious for failure. The two-piece design with crimped boots can’t handle the heat and pressure, and it’s only a matter of time before it leaves you stranded.

The factory cold side has its own issues, being made of plastic with an unreliable clamping system. But fear not! This kit replaces all those failure-prone components with our race-proven 5-layer silicone boots, ensuring you enjoy years of worry-free driving.

Included Components

This kit doesn’t stop there! To help get those exhaust gases out of the engine, we’ve included factory replacement 2-inch up pipes. Our up pipes are crafted from .120 inch wall tubing and feature the toughest bellows on the market, promising durability that lasts as long as your truck.

Stylish and Functional Coolant Tank

We also included a factory replacement coolant tank to keep your engine bay looking sharp. This aluminum tank comes with a built-in low coolant sensor, and to add a splash of color, we’ve thrown in our upper coolant tube. This not only looks great but also provides extra room for dual pumps, preventing any hose rubbing against the wheel.
