Transform Your Engine's Breathing

This kit is designed to help you and your engine breathe easy. With a mandrel bent 4 1/2 inch intake tube, you’ll experience impressive airflow gains. Plus, HSP's signature heat shield box works hard to keep unwanted hot air from sneaking into your cold air intake. Remember, for every 1-degree increase in intake air temperature, you could lose up to 3hp!

High Flow Turbo Mouthpiece

Our kit includes HSP's high flow turbo mouthpiece, allowing you to reroute your factory PCV system and ditch the factory resonator box. This change eliminates the pesky engine oil that can gum up your turbo and intake system. You'll also find 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, all designed for optimal performance.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you're probably aware of the factory hot side intercooler tube's reputation for failure. Its two-piece design, with crimped-on boots, often succumbs to heat and pressure. Don’t wait until it leaves you stranded! The factory cold side has its own limitations too, being made of plastic and featuring an unreliable clamping system.

Durable Replacement Components

This kit replaces all those failure-prone parts and comes equipped with our race-proven 5-layer silicone boots, ensuring years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can anticipate performance gains while keeping your engine temps in check. Plus, we’ve included a 2-inch passenger side up pipe featuring .120 inch tubing and the best bellow available on the market.
