   I'll have to take a picture of them once I remove them from the truck.  :)   
      
   I assumed that they last longer due to most engines being fuel injected and   
   computer controlled these days so there is less chance of running "too rich"   
   or "too lean".     
      
   Unless the original owner changed the plugs before 63k (which I doubt), they   
   have never been changed.  It has 145k on it right now.     
      
   I ran my original plugs in my Monte Carlo over 100k, too.  On that vehicle, I   
   do have a distributor however.
