Upgrade the air filter in your 2000-2021 Mercedes Sprinter 2.7L/3.0L Diesel with a new Drop-In Air Filter. 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. 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. Replace the factory air filter on your vehicle with a quality drop-in air filter from S&B Filters, AFE, K&N Engineering, and others 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.
