help is my air filter stock?
 

I have been running a HIFLO filtro HFA 1909 paper filter thinking it was as good or similar to OEM

Not sure what you are asking. HiFlo is obviously not stock. It'll do the job just fine if that's what you're asking. I recently put one in my VTR and it didn't fit very well.
