Your All-in-One Performance Kit

Are you on the hunt for a kit that truly has it all? Look no further! This impressive setup features a mandrel-bent 4.5-inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box. This clever addition keeps unwanted hot air from sneaking into your cold air intake. Just a 1-degree rise in intake air temperature can lead to a 3hp loss, so we’ve got you covered!

Turbo Mouthpiece & PCV System

Our 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 helps prevent engine oil from gumming up your turbo and intake system, keeping everything running smoothly. With 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, you’ll notice a significant boost in performance.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you might be familiar with the notorious factory hot side intercooler tube that often fails. Its two-piece design, with crimped boots, tends to give way under heat and pressure. Don't wait for it to leave you stranded! Our kit replaces all those failure-prone pipes and comes with race-proven 5-layer silicone boots, ensuring years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can expect improved performance while keeping engine temperatures in check.

Exhaust Efficiency & Engine Bay Aesthetics

To help clear out exhaust gases, we’ve included factory replacement 2-inch up pipes made from .120-inch wall tubing, featuring the toughest bellows on the market. These will stand the test of time alongside your truck. Plus, our factory replacement coolant tank not only keeps your engine bay looking sharp but also boasts an all-aluminum design with an integrated low coolant sensor. To add a splash of color, we’ve included an upper coolant tube that also provides extra room for dual pumps, preventing any hose rub against the wheel.
