Denso IK22 Spark Plugs

I've noticed that my car sometimes runs a little unevenly at low RPMs in 1st - based on some things I've read/heard this may mean I'm due for a spark plug replacement. My thought is 'why not upgrade?'

Looking around on here, I've seen the Denso IK22 mentioned as a good replacement/upgrade for spirited driving and autocross.
I see Denso IK22 and Denso IK22G online. Which is the correct part for a 2013 6MT? Denso IK22 #5310?
