I agree with 100k for most trucks, but the triton plug snappers.  The tritons I recommend 30 to 50 K.  I have not broken 1 yet at 50K. Knock on wood.  I have pulled out hundreds on GM's with iridium factory plugs with well over 100K and I can see both iridium tips are is tact and there are no misfire concerns related to the ignition system.
