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 4.5-inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box that keeps unwanted hot air from sneaking into your cold air intake. Just remember, for every 1-degree increase in intake air temperature, you can lose up to 3 horsepower!

Turbo Mouthpiece & PCV Rerouting

This kit includes HSP's high-flow turbo mouthpiece, which allows you to reroute your factory PCV system and remove the stock resonator box. Say goodbye to engine oil gumming up your turbo and intake system!

Durable Tubing for a Worry-Free Drive

Worried about the factory hot side intercooler tube on your 2011-2016 Duramax? You're not alone! The two-piece design with crimped boots is notorious for failure under heat and pressure, leaving you stranded when you least expect it. Our kit replaces all the unreliable piping with robust 3-inch mandrel bent hot side and cold side tubes, along with our race-proven max flow Y-bridge and turbo mouthpiece. You can drive with confidence, knowing that our 5-layer silicone boots will keep everything secure for years to come.

Efficient Exhaust Flow

To help expel exhaust gases effectively, we’ve included factory replacement 2-inch up pipes. Our up pipes are made with .120-inch wall tubing and the strongest bellows available, ensuring they’ll last as long as your truck does. Plus, we’ve added a sleek aluminum coolant tank that not only looks great but also features a low coolant sensor for peace of mind.

Stylish & Functional Additions

To add a splash of color to your engine bay, our kit comes with an upper coolant tube that also provides extra space for dual pumps, preventing any potential rubbing against the wheel.
