Your All-in-One Performance Kit

Are you on the hunt for a comprehensive performance kit? Look no further! This kit comes equipped with a mandrel-bent 4 1/2 inch intake tube designed to maximize airflow. Plus, with HSP's signature heat shield box, you can say goodbye to unwanted hot air sneaking into your cold air intake. Just a 1-degree increase in intake air temperature can result in a 3hp loss, so keeping things cool is essential!

Turbo Mouthpiece for Enhanced Functionality

Our kit features HSP's high-flow turbo mouthpiece, allowing you to reroute your factory PCV system and ditch the factory resonator box. This means no more engine oil gumming up your turbo and intake system!

Durable Tubing for Reliability

The factory hot side intercooler tube on your 2011-2016 Duramax is known for its failure-prone design. With crimped-on boots that can’t handle heat and pressure, it’s only a matter of time before you find yourself stranded. The factory cold side isn’t much better, being made of plastic with an unreliable clamping system.

Our kit replaces all those troublesome pipes with robust, race-proven 5-layer silicone boots, ensuring you enjoy years of worry-free driving. Coupled with our Max Flow Y-bridge and turbo mouthpiece, you can expect noticeable performance gains while keeping engine temperatures in check.

Up Pipes and Coolant Tank

To help expel exhaust gases efficiently, we’ve included factory replacement 2-inch up pipes. These pipes utilize .120 inch wall tubing and feature the toughest bellows on the market, promising longevity for your truck. Plus, we’ve added a factory replacement coolant tank to keep your engine bay looking sharp.

Our coolant tank boasts an all-aluminum design with an integrated low coolant sensor. And to add a splash of color, we’ve included an upper coolant tube that also provides extra space for dual pumps, eliminating any chance of the hose rubbing against the wheel.
