Your All-in-One Performance Kit

Are you on the hunt for a complete kit that truly has everything you need? Look no further! This kit features a mandrel bent 4 1/2 inch intake tube designed to maximize airflow, ensuring your engine runs smoothly. Plus, with HSP's signature heat shield box, you won't have to worry about unwanted hot air sneaking into your cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose up to 3 horsepower!

Turbo Mouthpiece Innovation

This kit also includes HSP's high-flow turbo mouthpiece, which allows you to reroute your factory PCV system and eliminate the factory resonator box. Say goodbye to unwanted engine oil gumming up your turbo and intake system! You'll appreciate the 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you're likely aware of the issues with the factory hot side intercooler tube. Its two-piece design with crimped-on boots is prone to failure under heat and pressure. It’s just a matter of time before it leaves you stranded. The factory cold side isn't much better, being made of plastic with an unreliable clamping system. Our kit replaces all of this failure-prone piping and comes with race-proven 5-layer silicone boots, giving you years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can look forward to noticeable performance gains while keeping engine temperatures down.

Efficient Exhaust Gas Management

To help your engine breathe easier, this kit includes factory replacement 2-inch up pipes. Our up pipes are built with .120 inch wall tubing and feature the toughest bellows on the market, ensuring they’ll 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 is made from all-aluminum and features a low coolant sensor for added convenience. To give your engine bay a pop of color, we also added an upper coolant tube. This tube not only looks great but provides extra room for dual pumps, eliminating the risk of hose rub against the wheel.
