The link provided in the second post shows the 51356 as the Wix oil filter for the Mitsubishi engine. This filter will work perfectly for you. Filters with just the Wix name on them are hard to source in my area. It's easiest for me to get the Napa or Carquest brand, which are Wix filters. As far as the hydraulic filter and air filter goes, it may be cheaper at the dealer.
