I know this is posted in second gen Legacy forum. I'm curious, however, whether this mod will be beneficial for EJ253 engine of 4th gen Legacy, 2.5i NA?

I'm planning to get my stock plugs replaced. I'm at 60K and I believe the previous owner never replaced it at 30K. I was already thinking of going with stock plugs (FR5AP-11) for simplicity, but, after reading this thread, I was wonder if it would be beneficial to run the plugs OP bought?
