Find a Pre-Filter for the cold air intake on your 2007-2008 Jeep Grand Cherokee 3.0L CRD. Shop from brands like AFE, K&N Engineering, S&B, Banks, and others at XDP and find the perfect pre-filter for your air filter. Find the right pre-filter for your intake system by matching up your filter part number, or by using the filter dimensions. Each pre-filter is manufactured from a breathable free-flowing material that will block contaminants and debris while allowing proper airflow to the engine. 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.
