I purchased another set from a national autoparts retailer and NGK dealer to compare against. They are almost identical with the exception of two key differences: 1. One of the individual box panels of the Amazon spark plugs reads "Assembled in Thailand." The box of the legit ones from the brick-and-mortar store reads "Made in Japan." 2. The spark plugs from Amazon are embossed "NGK" on the metal collar right above the washer. The embossing on the ones from the brick-and-mortar store reads "Japan." Do yourself a favor and purchase quality spark plugs from a legitimate source. By doing so you'll have the assurance you are installing parts that will perform (100K miles for real NGK spark plugs) and won't damage your vehicle. **Q: Are they already gap?** A: Yes, iridium plugs are gapped at the factory due to the high potential of scratching the tips when trying to gauge the gaps. If you do want to double check the gaps prior to installation, don't use the coin measuring tool, but one that won't put pressure on the iridium tips. **Q: Will these fit a 2011 Accord V6?** A: Yes **Q: This is original Ngk ?** A: Mine appeared to be after watching several videos on counterfeits. Then just to be sure, I called NGK USA customer service and gave them the plug number and lot number. They confirmed the lot number was valid. (This was all last year.) The NGK person asked me where I had purchased them and i told him Amazon. He stated that there were currently (again this was 2020) significant counterfeit issues on ebay purchased NGK Iridium plugs minimal issues on Amazon. Safest bet IMHO is to buy them from an auto parts retailer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Genuine NGK Units.
