Plugs Great/StaffAtThisP/UareGreat2
Wouldnt waste time or money on any plug but NKG,AC Delco or Motorcraft.These plugs last50-100k easy.Have seen them go to 185k before R/R.If your a Champion,Denso,bosch or Autolite plug person don't buy these because you wont get to service/repair your vehicle as often like your used to doing.Time and Time again perform flawless to 50-100k miles unlike autolite,denso,bosch or champion plugs.
