Evinrude E-TEC Gen1 and Gen2 fuel injector nozzle filter. Fits all E-TEC's and are very hard to find as they are not sold separately. Made of stainless steel these are used filters. However they are cleaned in a ultrasonic cleaner. Fully inspected. No reason to replaced your injector over a nozzle filter that has collapsed due to being dirty and the fuel pressure collapses it around the inner spring part of the nozzle assy.
