Where are the Royal Purple 20-820s?

[Tizzy]

Have the Royal Purple 20-820 been discontinued? They aren’t available anywhere. Im taking my last one off my 19 2500 6.4 and replacing it with an SRT filter.
Also, has anyone done a comparison between the Royal Purple 20-820, the SRT, and the Ford Racing filter?

Summit racing is showing "10 in stock". I'm seeing them in the wild on ebay & amazon also.

I'm having the same problem with the 10-2876 model - popular size for Hondas/Mazdas/Nissans/Subarus so a bit confused as to why it's out of stock everywhere
