Not genuine NGK!
Ordered 4. First thing that I noticed was that protective sleeves were short and did not protect outer electrode from damage. Surely enough gaps measured .019", .023", .030" and .031" (instead of "pre-gapped" .043"). Well, tried to adjust but that did not work well because after adjusting (with proper tool) ground and outer electrodes were misaligned (off center) and not parallel. That makes me think that these are just Made in China fake packed in fake Nissan boxes and sold as OEM. There are other indicators like print not centered, lack of talcum, finish quality etc. telling me that these are definitely not made by NGK.
