High-performance iridium spark plugs, set of 4. - Brand: DENSO - Model: V9110-5655 VFKH20 IRIDIUM TOUGH - Quantity: 4 pieces - Made in Japan Thank you for viewing. I purchased these about a year ago, but I realized I had the wrong model when I went to use them (^_^;) If anyone needs them, please take them. I will wrap them in bubble wrap and send them via Yu-Packet Post Mini (shipping from a convenience store), so I've discounted the price accordingly. I opened the box when I bought them, but they are of course unused.
