Air filter

One of my local tracts just posted a rule of NO AFTER MARKET AIR FILTERS. It did not specify if that applies to a certain class or not.

I run senior clone 375. Sorry for the stupid question but how do I tell if any of the 9 clean/ready to race air filters are after market?
 
your clone would still have to retain its factory air box to use the factory filter all these racing engines no longer have that attached.
