any recommendations on spark plugs for Montero?

I about to tackle this task. I see quite a few plugs listed for this vehicle on Advance Auto Parts website. Any recommendations?

This is a 2002 Montero XLS, 3.5L V6.

I haven't installed them yet but I bought NGK G Power (http://www.ngksparkplugs.com/products/spark_plugs/gpower.asp) plugs.
