Revitalize Your Engine with Our Premium Kit

This kit is designed to help both 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 keeps unwanted hot air from entering the cold air intake, ensuring your engine performs at its best. Remember, for every 1-degree increase in intake air temperature, you could lose around 3 horsepower!

Turbo Mouthpiece for Enhanced Efficiency

Our high-flow turbo mouthpiece gives you the flexibility to reroute your factory PCV system while eliminating the factory resonator box. This means no more engine oil gumming up your turbo and intake system. The kit features 3-inch mandrel-bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece for optimal performance.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you're likely aware that the factory hot side intercooler tube is notorious for failure. Its two-piece design, with crimped-on boots, often gives way under heat and pressure. Don’t wait for it to leave you stranded! The factory cold side isn't much better, being made of plastic and featuring an unreliable clamping system.

Worry-Free Driving Ahead

Our kit replaces all those failure-prone pipes and comes with race-proven 5-layer silicone boots, ensuring you enjoy years of hassle-free driving. Paired with our Max Flow Y-bridge and turbo mouthpiece, you can look forward to improved performance while keeping engine temperatures in check. We’ve even included a 2-inch passenger side up-pipe with .120-inch tubing and top-notch bellowing to withstand the heat.
