All-in-One Performance Kit

Are you on the hunt for a comprehensive kit that truly delivers? Look no further! Our kit features a mandrel bent 4 1/2 inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box, which effectively keeps unwanted hot air from sneaking into your cold air intake. Remember, for every 1-degree increase in intake air temperature, you could lose 3 horsepower. But not with this kit!

Turbo Mouthpiece Benefits

This kit also includes HSP's high flow turbo mouthpiece, giving you the chance to reroute your factory PCV system and remove that bulky factory resonator box. Say goodbye to engine oil gumming up your turbo and intake system! You’ll also enjoy 3-inch mandrel bent hot side and cold side tubes, complete with our max flow Y-bridge and turbo mouthpiece.

Upgrade Your Duramax

If you own a 2011-2016 Duramax, you know the factory hot side intercooler tube is prone to failure. The two-piece design with crimped boots doesn’t hold up well under heat and pressure, and it’s only a matter of time before it leaves you stranded. The factory cold side? It’s made of plastic and has a clamping system that just doesn’t cut it. Our kit replaces all those weak points with robust piping, and it comes with our race-proven 5-layer silicone boots, ensuring you enjoy years of worry-free driving. With the Max flow Y-bridge and turbo mouthpiece, you can expect noticeable performance gains while keeping engine temperatures down.

Durable Up Pipes and Coolant Tank

To help get those exhaust gases out efficiently, we’ve included factory replacement 2-inch up pipes. Made with .120 inch wall tubing and the toughest bellows on the market, these pipes are built to last as long as your truck. Plus, we’ve added a factory replacement coolant tank to keep your engine bay looking sharp.

Our coolant tank is crafted from all-aluminum and features an integrated low coolant sensor. To sweeten the deal, we’ve thrown in our upper coolant tube, adding a pop of color to your engine bay while providing extra space for dual pumps, ensuring the hose doesn’t rub against the wheel.
