Spark Plug Socket size

[silverFX]

I am tired and don't want to think anymore. So I will just give up and ask the question here.

What size spark plug socket do I need to buy for my FX35?

In the morning I hopefully will have my answer.

Stupid internet. Knowing my luck it would be in the owners manual.

Thanks.

In what ways, if any, can installing 'better' spark plugs improve performance?
Any hp or tq?
