Air filter cover?

I believe it shows screaming eagle on the side, I know sod all about air filters, covers, air intake etc but due to not having any service history for this bike I no nothing about what's been done,
Is this an after sales extra? Has this been changed for a better filter? How can I tell?
Is it better than a hyper charger, I have this wrinkle black hyper-charger from a previous bike which I think would look great on it:

It's just the cover, would need to get insides for it, how easy is it to fit on a sportster? Is it any good?*
Any info guys on these items would be great ;0) *
