This is the GrimmSpeed Dry-Con Performance Panel Air filter. This is a high-performance direct-OEM replacement panel filter that has been designed to flow more air while retaining optimal filtering capabilities. Although the factory panel does an excellent job of filtering, it can be restrictive even for a stock vehicle. The GrimmSpeed unit will allow the filter to flow more air while providing superior filtering protection and efficiency. This will allow the engine to breathe easier which will improve the overall performance all in a direct drop-in installation.
