Cold Air Inductions Intake for 2017-2019 GM 2500/3500 HD with 6.6L Duramax Diesel

Let your 6.6L Duramax breathe. The factory airbox is restrictive. This isn’t a guess; it’s a fact. If you use your truck for towing, hauling, or just want more out of it, this cold air intake system is the first and most effective mod you can do. We’ve installed these ourselves and the difference is real.

What This Intake Does For Your Truck:

Cooler, denser air means more efficient combustion. For your Duramax, that translates directly to useable gains. You’ll feel a sharper throttle response when you hit the pedal, especially when you’re hooked to a trailer. The engine can pull harder because it’s getting more oxygen. You’ll also hear a deeper, more pronounced turbo spool and intake sound—it’s all business.

The key is in the design. The thermal-coated intake tube and insulated aluminum air box work together to shield incoming air from engine bay heat. This reduces heat soak, which is a killer for performance, especially in summer or under heavy load. Cooler air is better air, period.

Built Right Here, Built Right.

This Cold Air Inductions kit is manufactured in the USA. We stock it because the quality and fit are spot-on. It bolts directly to your factory locations—no cutting, no guessing. The clear window on the airbox is a smart feature. You can check the high-flow filter’s condition with a look, no tools needed. When it’s time, cleaning and re-oiling is straightforward.
