Your All-in-One Performance Kit

Are you on the hunt for a performance kit that truly has it all? Look no further! This kit features a mandrel bent 4.5-inch intake tube designed to maximize airflow. Plus, with HSP's signature heat shield box, you can say goodbye to unwanted hot air entering your cold air intake. Did you know that for every 1-degree increase in intake air temperature, you could lose about 3 horsepower? With this kit, you can keep those numbers in check!

Key Features

One standout component is HSP's high flow turbo mouthpiece. This innovative piece allows you to reroute your factory PCV system while removing the factory resonator box. This helps eliminate engine oil from gumming up your turbo and intake system, keeping everything running smoothly.

The kit also includes 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece. If you own a 2011-2016 Duramax, you might be aware that the factory hot side intercooler tube is known for its failures. Its two-piece design with crimped boots often succumbs to heat and pressure, leaving you stranded. The factory cold side has its own shortcomings too, being made of plastic with an unreliable clamping system. Our kit replaces all those failure-prone parts and comes equipped with race-proven 5-layer silicone boots, ensuring years of worry-free driving.

Exhaust Efficiency

To help get those exhaust gases out efficiently, we’ve included our factory replacement 2-inch up pipes. These up pipes are crafted from .120-inch wall tubing and feature the toughest bellows on the market, guaranteeing longevity for your truck.

Stylish and Functional Coolant Tank

We didn't stop there! This kit also includes 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. To add a splash of color to your engine bay, we’ve included an upper coolant tube that also provides extra room for dual pumps, preventing any hose rubbing against the wheel.
