Replace your old and dirty air filter with a Drop-In Air Filter for your 2020-2023 Chevy/GMC 6.6L L5P Duramax. Most factory-style drop-in air filters are made with a paper filter media, and aftermarket performance air filters generally use a cotton-gauze media that requires filter oil, or a synthetic dry media. Drop-in air filters get their name from their designn as most have a "drop-in" installation and simply fit inside the factory air box. Shop for drop-in air-filters from manufacturers like S&B Filters, AFE, K&N Engineering, and others available at XDP. The air filter is a critical component in your vehicle and is designed to keep dust, debris, and contaminants out of your engine.
