💯% Authentic NGK Made in Japan.
Got these for my 2016 Subaru Crosstrek. You can't go wrong with NGK, these are 💯% AUTHENTIC, and made in Japan, unlike other NGK plugs that may be sold by other sellers which could be made in Thailand. The Subaru Crosstrek is running like a brand new vehicle after I put these puppies in it.

Worked like a charm
Worked like a charm. The box and packaging were adequate from keeping the gaps of the plugs from being squished.
