Replace the old air filter in your 2014-2019 Ram 1500 3.0L EcoDiesel with a Drop-In Air Filter. 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. Air Filters provide your engine with clean air by trapping harmful contaminants such as dust and debris before entering the intake. In most cases an oe-style drop-in air filter will be made with paper filter media, where an aftermarket air filter typically features a synthetic media, or a cotton gauze design that may be dry or oiled. Shop for drop-in air-filters from manufacturers like S&B Filters, AFE, K&N Engineering, and others available at XDP.
