Your Ultimate Performance Kit for Duramax

Are you on the hunt for a performance kit that truly has it all? Look no further! Our kit features a robust mandrel bent 4 1/2 inch intake tube, designed to maximize airflow and give your engine the boost it needs. Plus, with HSP's signature heat shield box, you can say goodbye to unwanted hot air sneaking into your cold air intake. Remember, every 1-degree rise in intake air temperature can lead to a 3hp loss—so keeping things cool is essential!

High Flow Turbo Mouthpiece

This kit also comes equipped with HSP's high flow turbo mouthpiece, which allows you to reroute your factory PCV system and ditch that bulky factory resonator box. This means no more engine oil gumming up your turbo and intake system—what a relief!

Durable Hot and Cold Side Tubes

We understand that the factory hot side intercooler tube on your 2011-2016 Duramax is notorious for failure. Its two-piece design and crimped-on boots often give out under heat and pressure, leaving you stranded. The factory cold side isn't much better, being made of plastic and featuring an unreliable clamping system.

Our kit replaces all those failure-prone pipes with sturdy 3-inch mandrel bent hot and cold side tubes. You’ll also get our race-proven 5-layer silicone boots, ensuring years of worry-free driving. With the Max flow Y-bridge and turbo mouthpiece included, 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 are built with .120 inch wall tubing and the toughest bellows available, promising durability that matches your truck's lifespan. Plus, our factory replacement coolant tank not only keeps your engine bay looking sharp but also features an all-aluminum design with an integrated low coolant sensor.

And to add a splash of color, we’ve thrown in an upper coolant tube that creates extra space for dual pumps, eliminating the risk of hose rubbing against the wheel. Talk about a win-win!
