The "Oil Easy Wrench" is specifically designed to remove the oil filter on any aircraft using the Teledyne Continental IO-520 or IO-550 engine. In fact, it is a universal oil filter wrench that works great on any piston engine airplane! Recommended at the Malibu Mirage Owners and Pilots Association (MMOPA) maintence seminar!!! On IO-520's & IO-550's engines, it's the only wrench that can get between the top of the oil filter and the pressure pump and still provide enough leverage to remove the old (usually stuck) oil filter by hand. And because you are able to remove the old filter without any damage, your inspections of the old filter are more accurate, without any contamination from more extreme filter removal methods.
this thing saved my bacon! Theres no way to get a conventional wrench on a tempest 109 on my io-550. Theres just not enough clearance. This wrench fits perfect and really mitigates the mess of other ways to get the 109 off. Pro-tip: use a folded up rag as a makeshift handle pad for the really stuck filters.. it will save your hands.
