Complete Performance Kit for Your Duramax

Are you on the hunt for a 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, HSP's signature heat shield box works wonders by keeping unwanted hot air from interfering with your cold air intake. Just a 1-degree increase in intake air temperature can lead to a 3hp loss, so this feature is a game-changer!

High-Flow Turbo Mouthpiece

One of the standout components 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 prevent engine oil from gumming up your turbo and intake system. You'll also find 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 probably 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 has its own issues, being made of plastic with a clamping system that just can’t be trusted. This kit replaces all those failure-prone pipes and comes with our race-proven 5-layer silicone boots, ensuring you enjoy 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.

Robust Up Pipes for Improved Exhaust Flow

To help get those exhaust gases out efficiently, this kit includes our factory replacement 2-inch up pipes. Made with .120 inch wall tubing and the toughest bellows available, these up pipes are built to last as long as your truck. And don’t worry, we’ve also included a factory replacement coolant tank that not only performs well but keeps your engine bay looking sharp.

Stylish and Functional Coolant Tank

Our coolant tank boasts an all-aluminum design with an integrated low coolant sensor. To add a splash of color to your engine bay, we’ve included our upper coolant tube, which also provides extra space for dual pumps, reducing the chance of hose rub against the wheel.
