Your All-in-One Performance Kit

Are you on the lookout for a kit that truly has everything you need? Look no further! This kit boasts a mandrel-bent 4 1/2 inch intake tube designed to maximize airflow, ensuring your engine gets the breath of fresh air it deserves. Plus, with HSP's signature heat shield box, you can wave goodbye to unwanted hot air sneaking into your cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose up to 3 horsepower!

High Flow Turbo Mouthpiece

But that's not all! This kit comes with HSP's high flow turbo mouthpiece. This nifty addition allows you to reroute your factory PCV system while getting rid of that bulky factory resonator box. Say goodbye to engine oil gumming up your turbo and intake system!

Durable Tubing for Reliable Performance

We all know that the factory hot side intercooler tube on your 2011-2016 Duramax can be a headache. Its two-piece design with crimped-on boots is prone to failure under heat and pressure, and it’s just a matter of time before it leaves you stranded. The factory cold side isn’t any better, made from plastic and featuring a clamping system that just doesn’t cut it.

This kit replaces those troublesome pipes with robust, reliable components. You’ll receive our race-proven 5-layer silicone boots, ensuring years of worry-free driving. Paired with our Max Flow Y-bridge and turbo mouthpiece, you can expect noticeable performance gains while keeping engine temperatures down.

Up Pipes and Coolant Tank

To help your engine breathe easier, we’ve included factory replacement 2-inch up pipes. Our up pipes are crafted from .120 inch wall tubing and feature the toughest bellows on the market, promising durability that lasts as long as your truck. And don’t worry about your engine bay looking shabby; we’ve got you covered with our all-aluminum coolant tank, which includes a low coolant sensor for added peace of mind.

To add a splash of color to your engine bay, we’ve also included an upper coolant tube. This not only looks great but also provides extra room for dual pumps, preventing any hose rubbing against the wheel.
