Default Spark Plug Recommendation

My friend has a 2000 T/A, tonight we pulled the plugs on it and tomorrow we'll be going for new plugs....what do you guys recommend and what should I gap them?
It had AC 41-952
25321615
Are the factory plugs? I just measured one and the gap is .062, why so much?

Pulsar plugs!!!!


But in all seriousness, seems most everyone around here goes for the NGK TR55's or the TR55IX (iridium) plugs.
