Fleetguard introduced a "user-friendly" filter design, using polymers to make it more dent-resistant than metals. Current filters in the FF, FS, LF and MK series will be replaced by new numbers with the same letter prefixes. These will be for applications on Case, Ford, GMC, International, Komatsu, KHD, Volvo and other engines. Filters have an easy-grip surface with ribs, flat "no-spill" bottom, and built-in one-way socket for removal with a ½-inch wrench.
