Transform Your Engine's Breathing

This kit is designed to help you and your engine breathe a little easier. With a mandrel-bent 4.5-inch intake tube, you can expect significant airflow improvements. Plus, HSP's signature heat shield box works tirelessly to keep unwanted hot air from sneaking into your cold air intake. Remember, for every degree the intake air temperature rises, you could lose up to 3 horsepower!

High Flow Turbo Mouthpiece

Included in this kit is HSP's high flow turbo mouthpiece. This clever addition allows you to reroute your factory PCV system and remove the factory resonator box, which helps prevent 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, you’re set for some serious performance boosts.

Durable Replacement Parts

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, with crimped-on boots, tends to fail under heat and pressure, leaving you stranded when you least expect it. The factory cold side isn’t much better, as it’s made of plastic and has a clamping system that’s anything but reliable.

This kit replaces all those failure-prone components with robust parts. You'll receive our race-proven 5-layer silicone boots to ensure years of worry-free driving. When paired with our Max flow Y-bridge and turbo mouthpiece, you can anticipate performance gains while keeping those engine temperatures in check. We’ve also thrown in a 2-inch passenger side up-pipe featuring .120-inch tubing and the best bellow on the market.

Factory Up-Pipe Concerns

The factory up-pipe is known to fail at the riser due to excessive heat and pressure. Our kit addresses this issue head-on.
