All-in-One Performance Kit

Are you on the hunt for a performance kit that truly has it all? 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. This clever addition 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!

Turbo Mouthpiece and Enhanced Airflow

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. Say goodbye to engine oil gumming up your turbo and intake system!

With 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, you’ll be ready for an impressive performance boost.

Upgrade Your Duramax

If you own a 2011-2016 Duramax, you know that the factory hot side intercooler tube is notorious for failure. Its two-piece design, with crimped-on boots, often succumbs to 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 durable options and includes race-proven 5-layer silicone boots, ensuring you enjoy years of worry-free driving.

With our Max flow Y-bridge and turbo mouthpiece, you can expect to see performance gains while keeping your engine temperatures in check.

Exhaust Efficiency and Aesthetic Appeal

To help your engine breathe easier, we've included factory replacement 2-inch up pipes that utilize .120 inch wall tubing and the toughest bellows available. This means they’ll stand the test of time, just like your truck. Plus, we’ve added a factory replacement coolant tank to keep your engine bay looking sharp. Our all-aluminum coolant tank features a built-in low coolant sensor, and we’ve topped things off with an upper coolant tube that adds a pop of color while providing extra space for dual pumps—no more worries about hose rub!
