I purchased these for an ACR50 Estima, but due to a mix-up, I ended up with 8. I'm selling the remaining 4, excluding the 4 I used. These are genuine, not the fakes that have been circulating online recently. I don't mind keeping them as spares, so I can't offer a huge discount, but I'm listing them in case anyone is having trouble finding them during the New Year's holiday. I will ship them the same day you purchase them. High-performance iridium spark plugs IK16, providing excellent ignition performance. - Brand: DENSO - Model: IK16 - Type: Iridium Spark Plug - Quantity: 4 Thank you for looking.
