V8 Iridium Spark Plugs

[the dutch man]

I'm looking to change the plugs on my 03 V8. I'm down to the Denso SK20R11 or the IK20. I'm wondering which one I should use. the SK is $7.59 per plug and IK is $10 per plug. Not sure which one is installed as a stock on the V8. Anyone changed their's yet?

I've read that the NGK's don't hold up as well as the Denso's. The manual lists either an NGK or Denso. I'm going to pull one out of my truck this weekend and see what's installed from the factory. Just curious if anyone had changed them on the V8, which needs iridium plugs, and what the used.

There is a label on the driver's side valve cover that says what plugs to use. I just changed mine, it was pretty easy.
