Phearable tune spark plug question.

[nodnarb901]

I just got a revised tune from Phearable, and in the instructions it said

Spark Plugs:
You should be using NGK ILZKAR8H8S gapped at .026

Are these the OEM plugs?

The owner’s manual says NGK ILZKAR8J8SY.

Ok thank you, looks like I’ll be picking up a set of new plugs. ?
