    Get new plug
  

*by E***C on Reviewed in the United States on July 14, 2013*

I bought a plug from the local TSC and got home to find that I needed two for my parents lawn mower so I ordered one from amazon.  After installation, I noticed the engine started easier and seemed to run smoother.  I would recommend it to anybody.  It's been over 2 months from first use with no problems.
