Excellent plugs, superb performance
Exactly as described at a decent price. I've found over my decades of doing my own tune ups, the one thing you can't skimp on when tuning up your vehicle, plugs and its shows if you do. Out of the box, all 4 were gapped correctly. Ease of installation depends on your vehicle and ones mechanical ability with PATIENCE. 100% compatible with my vehicle, be sure to match you numbers. Overall 5 stars for performance and price.

💯% 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.
