Replace the old air filter in your 2016-2019 Nissan Titan XD 5.0L Diesel with a Drop-In Air Filter. 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. Air Filters provide your engine with clean air by trapping harmful contaminants such as dust and debris before entering the intake. Shop for drop-in air-filters from manufacturers like S&B Filters, AFE, K&N Engineering, and others available at XDP. Drop-in air filters are aptly named as they have a "drop-in" installation that allows them to fit inside of your factory air box.
