Keep your filter safe from sand, mud, and other debris when you purchase a Pre-Filter to your cold air intake on your Gas Vehicle. Pre-filters are manufactured from a breathable material that lets air through while blocking large debris and contaminants. A pre-filter is installed over your air filter and helps to extend cleaning intervals while also blocking out large debris that might otherwise damage your air filter. 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. Finding the right pre-filter for your intake can be done by matching up filter dimensions or by using the corresponding filter part number.
