Transform Your Engine's Breathing

Say goodbye to engine strain with our fantastic intake kit! This setup features a mandrel-bent 4.5-inch intake tube that significantly boosts airflow, paired with HSP's signature heat shield box. This clever design keeps unwanted hot air from sneaking into your cold air intake, ensuring your engine breathes easy. Remember, for every 1-degree rise in intake air temperature, you could lose 3 horsepower!

High Flow Turbo Mouthpiece

Our kit comes equipped with HSP's high-flow turbo mouthpiece, which gives you the flexibility to reroute your factory PCV system. Plus, it helps you remove the factory resonator box, preventing pesky engine oil from 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, performance gains are just around the corner!

Upgrade Your Duramax

If you own a 2011-2016 Duramax, you might already know that the factory hot side intercooler tube is known for its failures. The two-piece design, with crimped-on boots, often gives way under heat and pressure, leaving you stranded. The cold side isn’t much better, being made of plastic with a clamping system that can’t be trusted.

Reliable Replacement Parts

Our kit replaces all those failure-prone pipes, featuring race-proven 5-layer silicone boots that promise years of worry-free driving. With the included Max Flow Y-bridge and turbo mouthpiece, you can expect a noticeable boost in performance while keeping those engine temperatures in check. We’ve even added a 2-inch passenger side up-pipe with .120-inch tubing and the best bellow on the market to ensure durability.
