Yes there are many sources. But one that frequently pops up here is smart madness. I found the link for the filter below.
They have the OEM filters in stock and several aftermarket air filters. Call them directly if you have questions.
Napa has Smart filters. Oil filter is part# 7040. Cabin is #9351. Air cleaner is #9301. The first two are available now and the Air should be out by summer.
