Looks like wix does not do this filter as of yet.

The only cross to the Generac filter is a Wix 49227. Costs between 7.99 to 16.99 online. Don't throw away outer pre-filter (OC3040) wrap. Reuse pre-filter by just cleaning it with soap and water, rinse and dry.
That number, 513211, interchanges to a WIX 51374.
WIX - Oil FilterPart # 57145
I have found a filter, available from NAPA, which seems to match perfectly. NAPA's part number is 7181; the WIX number is 57181.
NAPA 5010
For the Generac 5500XL, if the original oil filter (part number 70185) is discontinued, you can use an alternative filter such as the Generac part number 070185 or a compatible aftermarket filter like the WIX 51348 or NAPA 1348. Always ensure that the filter has the correct dimensions and specifications for your generator. It's advisable to consult with a local dealer or a small engine repair shop for the best alternative options.
