Spark Plugs

What brand of spark plugs are good to use? How often should they be changed? I have the NGK iridium IX in my liberty currently and i'm coming up on 30k miles.

UPDATE: I have an 08 Libby

regular champion plugs are perfect for a Jeep. nothing fancy or NASCAR quality, leave that to crappy Hummers

The spark plugs are NGK ZFR6F-11G 6987. Amazon.com: NGK (6987) ZFR6F-11G V-Power Spark Plug, Pack of 1: Automotive . These are what i used, i only stick with OEM on the spark plugs, its not worth buying the expensive ones.

I also use the stock NGK plugs. I've changed them twice already at 30K and 60K without any problems and the all the plugs have worked great as far as I can tell. No need to pay extra for anything else.
