Exclamation Help E90 Error Code P0303 Cylinder 3 Misfire

Hey I have a BMW E90 2011 323i. Yesterday my car started misfiring and stumbling while stopped. Engine light turned on I got the code P0303 Cylinder 3 misfire. I ordered spark plugs online from

This is what i purchased: BOSCH FR7NPP332 (OEM#12122158253)

According to my car came with (OEM#12120035915)

Now I'm thinking if I ordered the wrong plugs and if I shouldve bought NGK PLZFR6A11S (OEM#12120035915) instead:

Will the ones I purchased fit my car even tho it has a different OEM#?

Please advise,
Thank you.
