DENSO IRIDIUM TOUGH Denso Iridium Tough spark plugs VFKB16 (V9110-5664), set of 4, unused and new. I no longer have a use for these, so please feel free to purchase them. Shipping is included, so no further discounts are possible. Please check the manufacturer's website for compatibility. I am not an expert, so I may not be able to answer questions regarding compatibility. (I can answer questions about the condition of the product to the best of my ability.) Please confirm compatibility yourself before purchasing. Although these are unused, please understand that they have been stored by an individual. (Please forgive any minor scratches that may have occurred during storage.) For those seeking a perfect item or who are overly concerned, please refrain from purchasing. Shipping will be via Yamato Easy Delivery, with shipping costs covered by me. Due to the thickness of the package, I will wrap each spark plug individually in bubble wrap and ship them without wrapping the entire box in bubble wrap. I am not responsible for any problems that may arise from using this product, regardless of whether it is compatible or not. (Please confirm compatibility and installation at your own risk.) If there is no response to questions or inquiries within 24 hours, you will be added to the block list. DENSO Denso Iridium Tough IRIDIUM TOUGH VFCH16 V9110-5664 V91105664 Spark plugs
