    Great sparkplugs
  

*by A***R on Reviewed in the United States on 1 July 2024*

Changed the sparkplugs (same AC Delco Iridium plugs) on my 2005 GMC Canyon which had almost 100,000 miles on them.  The truck ran fine but with the new plugs I have more zip and it's running smoother.  Haven't put enough miles on to check the mpg difference yet.
