I purchase the filter from Dinan. They are reusable. They can be cleaned and re-oiled. I use the K&N oil. Be sure to oil as directed. Too much oil will contaminate the MAF wires. I assume K&N has a match. Would need to measure diameter of opening and overall length so it fits, haven't tried that. Yours looks like oil is gone. When cleaned and oiled properly with K&N oil they take on a light pink cast. Can clean with soapy water and a brush to get down into the pleats.
