Your Ultimate Performance Kit Awaits!

Are you on the hunt for a kit that truly has everything you need? Look no further! Our performance kit features a mandrel-bent 4 1/2 inch intake tube designed to maximize airflow, ensuring your engine breathes easy. Plus, with HSP's signature heat shield box, you can say goodbye to unwanted hot air entering your cold air intake. Just a 1-degree increase in intake air temperature can lead to a 3hp loss, so keeping things cool is essential!

Turbo Mouthpiece for Enhanced Efficiency

This kit also includes HSP's high-flow turbo mouthpiece, which allows you to reroute your factory PCV system and remove the factory resonator box. This means less engine oil gumming up your turbo and intake system, leading to a smoother performance.

Durable Design for Long-lasting Performance

Worried about the factory hot side intercooler tube on your 2011-2016 Duramax? You're not alone! The original two-piece design is notorious for failure, often leaving you stranded due to crimped boots that can't handle heat and pressure. Our kit replaces all the failure-prone piping with robust components, including 3-inch mandrel-bent hot side and cold side tubes, along with our race-proven 5-layer silicone boots. With this upgrade, you can enjoy years of worry-free driving!

Exhaust Efficiency and Aesthetic Appeal

To help your engine breathe easier, this kit comes with factory replacement 2-inch up pipes. Crafted from .120 inch wall tubing and featuring the toughest bellows on the market, these up pipes are built to last. And let's not forget about our sleek all-aluminum coolant tank, which not only keeps your engine bay looking sharp but also includes a low coolant sensor for added peace of mind. To top it off, we’ve added an upper coolant tube that adds a splash of color while providing extra space for dual pumps—no more worrying about hose rubs!
