GM did an incredible job with the 2017-2019 Duramax airbox design, going so far as to include a hood air scoop. However, stock parts will never be able to perform as well as aftermarket parts. Air intakes and filters from manufacturers such as AFE, S&B, or Banks will produce adequate airflow that will wake your engine up. This simple modification will improve your truck's performance, efficiency, and longevity! And if you desire even more power, a tuner utilizes the intake and the filter, optimizing the airflow for even more power output.
Heavyweight Diesel stocks everything you need for your L5P Duramax; cold air intakes, high-quality filters, and cleaning kits. Note that air intakes and filters differ significantly, and you should purchase one designed specifically for your truck. If you get overwhelmed by the variety of choices, feel free to reach out to our Heavyweight Diesel technicians for support!
