2020-2024 GM Duramax L5P Cold Air Intake Kits

The premium 6.6L Duramax L5P under the hood of your aggressive 2020-2024 GM 2500 or 3500 truck may be one of the most efficient diesel engines on the market, but it's always hungry for more air. The first place you should be looking to improve airflow is the addition of a premium Cold Air Intake system that allows your engine to breathe much easier. Some intakes feature dual air inlets which maximizes airflow and results in improved power, performance, and throttle response on your heavy-duty GM Sierra/Silverado. Most of these kits also come standard with larger and reusable air filters that better protects your engine from contaminants while helping you save a bit of cash in the long run. Better yet, these intake systems are super easy to install as they come designed as a direct replacement of your factory units, making for a simple job you can complete at home. Get more efficiency out of your 6.6L Duramax L5P engine with any of the high-quality Cold Air Intake Kits offered right here at Alligator Performance!
