Give Your Engine a Breath of Fresh Air

This kit is designed to help both you and your engine breathe easier. With a mandrel-bent 4.5-inch intake tube, you’ll experience significant airflow improvements. Plus, HSP's signature heat shield box keeps unwanted hot air from entering the cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose about 3 horsepower. That’s why this kit also includes HSP's high-flow turbo mouthpiece.

Say Goodbye to Engine Oil Issues

This turbo mouthpiece allows you to reroute your factory PCV system and remove the stock resonator box, which helps prevent engine oil from gumming up your turbo and intake system. You’ll appreciate the 3-inch mandrel-bent hot side and cold side tubes, complete with our max flow Y-bridge and turbo mouthpiece.

Upgrade from Factory Components

For 2011-2016 Duramax models, the factory hot side intercooler tube is notorious for failing. Its two-piece design, complete with crimped boots, often gives out under heat and pressure. Unfortunately, it’s just a matter of time before it leaves you stranded. The factory cold side isn’t much better, made of plastic with an unreliable clamping system.

Reliable Performance for Worry-Free Driving

This kit replaces all those failure-prone components, coming equipped with our race-tested 5-layer silicone boots to ensure years of reliable driving. With our Max flow Y-bridge and turbo mouthpiece, you can expect improved performance while keeping engine temperatures in check. Plus, we’ve included a robust 2-inch passenger side up-pipe featuring .120-inch tubing and the best bellow available on the market.

Avoid Up-Pipe Failures

The factory up-pipe is often susceptible to failure at the riser due to excessive heat and pressure, but with our upgraded components, you can drive with confidence.
