2017-2019 GM 2500HD/3500HD 6.6L L5P Duramax Cold Air Intakes

The more airflow you provide a diesel engine, the more power it will be able to throw down for your 2017-2019 GM Duramax L5P. The easiest way to give your GM 2500HD or 3500HD truck more airflow is with the addition of an aftermarket cold air intake. The right cold air intake system allows your engine to breathe much easier which results in improved power, performance, and throttle response for every situation. Most of these aftermarket intakes kits come standard with larger air filters that better protects your 6.6L Duramax engine from contaminants, promoting long-lasting engine and component life. All of these GM Sierra/Silverado intake systems are super easy to install, letting you add some drop-in power in a hassle-free package. GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax.
