Transform Your Engine's Breathing

This kit is designed to help both you and your engine breathe easy. With a mandrel-bent 4 1/2 inch intake tube, you can expect significant airflow improvements. Plus, HSP's signature heat shield box works to keep unwanted hot air from sneaking into your cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose around 3 horsepower!

Turbo Mouthpiece Benefits

The kit includes HSP's high-flow turbo mouthpiece, which allows you to reroute your factory PCV system while removing the factory resonator box. This change helps prevent engine oil from gumming up your turbo and intake system, keeping everything running smoothly. You'll also find 3-inch mandrel-bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece.

Say Goodbye to Factory Limitations

If you own a 2011-2016 Duramax, you might be familiar with the issues surrounding the factory hot side intercooler tube. Its two-piece design, complete with crimped-on boots, is known for failing under heat and pressure. Unfortunately, it’s just a matter of time before it leaves you stranded. The cold side has its own drawbacks, being made of plastic and featuring an unreliable clamping system.

Worry-Free Driving Awaits

This kit replaces all the failure-prone piping, bringing you peace of mind with our race-proven 5-layer silicone boots designed for durability. When paired with our Max flow Y-bridge and turbo mouthpiece, you’ll notice improved performance while keeping engine temperatures in check. Plus, we’ve included a 2-inch passenger side up pipe made from .120 inch tubing, featuring the best bellow on the market to prevent failure from excessive heat and pressure.
