Plugs verified by NGK to be authentic
2007 Toyota FJ Cruiser. LFR6AIX-11 (stock number 6619). NGK makes truly great products and the result is many fake products are on the market. I sent pictures of the plugs to NGK for authentication and the reply was positive. NGK corporate is really good about taking the time to help you, they are very nice with very quick replies. Overstock Direct is an authorized reseller on Amazon, however, the Visit the NGK Store link associated with Overstock Direct has no association with NGK corporate. Having said that, I am happy with the purchase I made. I will post the pictures I sent to NGK. Look at the way the Iridium positive electrode post is shaped. It is cone shaped with a small protruding nipple on its center The numbers are on the plug’s hex base, vivid, deep and clear to read. The lines going around the porcelain top are sharp, vivid and not washed out. Now you know how to spot fake NGK Iridium plugs. I will purchase from Overstock Direct again. Hope this helps.
