Complete Kit for Your Duramax

If you're on the hunt for a comprehensive kit that truly delivers, you've come to the right place! This package features a mandrel-bent 4.5-inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box that keeps unwanted hot air from sneaking into your cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose up to 3 horsepower!

Outstanding Features

This kit also includes HSP's high-flow turbo mouthpiece. You’ll find 3-inch mandrel-bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, ensuring your engine performs at its best.

Say Goodbye to Factory Failures

We all know that the factory hot side intercooler tube on your 2011-2016 Duramax can be a headache. Its two-piece design with crimped-on boots is prone to failure under heat and pressure, leaving you stranded when you least expect it. The factory cold side isn't much better, made from plastic and relying on an unreliable clamping system.

Our kit replaces all those failure-prone components with robust options that include race-proven 5-layer silicone boots, giving you years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can anticipate noticeable performance gains while keeping engine temperatures in check.

Efficient Exhaust Gas Management

To help with exhaust gas evacuation, this kit comes with factory replacement 2-inch up pipes. We use .120-inch wall tubing and the toughest bellows available, ensuring they 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

Our coolant tank boasts an all-aluminum design and features a built-in low coolant sensor. To add a splash of color to your engine bay, we’ve also included an upper coolant tube. This tube not only looks great but also provides extra room for dual pumps, preventing any hose rubbing against the wheel.
