Product Description

  • Iridium offers better engine idle stability and smoother performance
  • Iridium allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration
  • Iridium fine-wire electrode helps improve ignition of the fuel and burns away carbon deposits on the tip of the plug as they form, to help improve fuel economy
  • One piece suppressor seal blocks radio frequencies that can affect vehicle electronics
  • Suppressor seal meters spark energy for longer electrode life and seals against combustion leakage

Worked great in my 2012 Chevy Cruze Eco. I gapped them a little higher to .030 and car runs super smooth.
These are direct replacement for factory plugs on my 2005 Suburban 5.3L V-8. Work perfect no issues. Would buy again.
These plugs work great. Mileage was not much improved but was glad I replaced them on my 2012 Cruze ECO with 108,000 miles.
