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?

I was looking to get the IK22s, not the stock replacement. Like I said, trying to go a step colder for spirited driving and autocross.
I guess 5310 is the correct part number for IK22s that work on our car?

Not that Honda has a billion dollar engine development program or anything and makes some of the most reliable engines out there. They might know best what sparkplugs to use on an otherwise stock engine.

Lol my engine is not stock.

... as if there's no such thing as mechanical tuning (Plus, Honda engineers on a hybrid designed for high mileage aren't always focusing on performance)

the Denso IK22s are well documented on here -
Also, be careful with that level of salt in your daily diet, can be bad for your health.

Was just trying to get the part number lol

1) please consider the definition of the word "stock"
2) because you didn't bother to read it the first time around, let's try again :D
