Pre-Filters help to prevent sand, mud, and dirt, from contaminating the air filter in your 2014-2018 Jeep Grand Cherokee 3.0L EcoDiesel. XDP carries pre-filters from manufacturers such as AFE, K&N Engineering, and many more! Find the right pre-filter for your intake system by matching up your filter part number, or by using the filter dimensions. A pre-filter installs tightly over your air filter and serves as the first line of defense to keep larger debris out of your filter media and help extend cleaning intervals. Pre-filters are manufactured from a breathable material that lets air through while blocking large debris and contaminants.
