Transform Your Engine's Breathing

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

High Flow Turbo Mouthpiece

Our high flow turbo mouthpiece is a game-changer! It allows you to reroute your factory PCV system and remove that bulky factory resonator box. This means no more engine oil gumming up your turbo and intake system. With 3-inch mandrel-bent hot side and cold side tubes, alongside our max flow Y-bridge and turbo mouthpiece, you’re set for success.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you might be familiar with the notorious factory hot side intercooler tube. Its two-piece design, with crimped-on boots, is prone to failure 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 from plastic and featuring an unreliable clamping system.

Reliable Replacement

Our kit replaces all those failure-prone components, and it comes with race-proven 5-layer silicone boots to ensure years of worry-free driving. With the Max flow Y-bridge and turbo mouthpiece, you can expect improved performance while keeping your engine temps down. We’ve even included a robust 2-inch passenger side up pipe, featuring .120 inch tubing and the best bellow available on the market.
