If it's the dry filter, you can clean it and reuse it. As long as it doesn't get damaged, it should last a good long time, and certainly more than 50k miles. I installed AEM dry filters in our company trucks in Afghanistan because it was so dusty there and stock paper filters were useless, and we washed those filters out every 30 days or sooner depending on how much driving we did.
It should tell you in the owners manual whether or not it needs to be oiled (and should tell you the p/n of the service kit that contains the oil and cleaner for it).
Based on what I found in the FCA manual, it says to replace the air filter at 50,000 miles, so I'm gonna say it's the dry filter. The oiled ones in the Demon said to clean them and re-oil them, and gave you the p/n for the kit to do it. Chrysler has since discontinued that kit. I have the oiled filter in my car and switched it over to the dry filter just so I don't have to deal with the whole oiling fiasco
Here is the link to the Supplemental manual for 2019 Challengers, and if you look starting around page 168 you will find the listing for the 6.2L Supercharged engine and it's maintenance schedule. Hope this helps.
