Bought some NGK Iridium plugs to put in the 2014 Tacoma and 2008 Tundra back in 2017. Both vehicles can take the same plug. I found out today thanks to BITOG that the plugs are counterfeit. The plugs have less than 40,000 on them and I was shocked at the level of wear for a Iridium plug. So instead of ordering them online I went up to Autozone a Authorized Reseller and purchased 6 new, identical plugs. I changed them out in the Tacoma the Tundra will have to wait for another day and won't get used until they are changed. I called NGK and confirmed with them they are fakes. My advice is if you have changed plugs and didn't get them from a authorized reseller you may want to check them. There is no telling what could happen if you leave them in.
