  • Not Long Life Iridium. These are basic plugs. Description wrong.
The Amazon title and description are wrong. These are not iridium plugs. They are the standard plugs. The Iridium Long-Life Spark Plugs are the Denso (3441) SXU22HDR8.

  • Ask your mechanic first, don't think you're helping by buying parts.
Although they were Iridium's they didn't fit my Kia, made the car miss fire. Had to purchase Platinum Iridium's. Car ran perfect with the right plugs.

  • Not iridium spark plugs

  • Not as advertised... Not iridium
It's a good replacement for my Smart car, but it ain't iridium. I will go ahead and install them, but Amazon needs to quit calling them iridium. Genuine iridium denso part is IXU22HDR9. This XU22HDR9 is Denso's U-groove standard plug. It's a good price and a good plug, and I'm going to install them anyway, but one star for misrepresentation! ... show more
