Spark plug help

I changed my plugs at 20k miles. I'm now at 53k miles. I changed to denso iridium plugs. Pulled them to check them out the other day. wanted to post pics to see what you guys though. Burning right or to rich/lean?? Any info. helpful. Thanks

 

look just fine to me..

 

hope so. theyre really white and i read on the interwebz that thats a sign of being too lean. hope not. thanks yosh

 

wait, why do you even care...didnt you say you were selling the truck in your unichip thread??

 

Yea, looks like my lil brother is gonna get it. Just got married and had a little girl. Needs the room. Trying to make sure its in good condition mechanically before he gets it. He's not handy at all.

 

Not sure if this is the case on these truck but many manufacturers are moving to leaner AFR's to increase fuel economy..
