it's what the manufacturer wants
This is exactly the same spark plug that I found inside my Chevy Volt engine. It came packed in a box. So no problem really. But the ad on site shows picture of 4 spark plugs, while you get only one. But you're paying the cost of 1, and while it can be lower, it's reasonable price per one. But still a bit misleading. I had to buy 2 more.

Price for one but advertised as for four. You might receive four or one pack or both!
Product is great. Made in Japan and worked perfectly with my 2017 Chevy Volt. The one star is for Amazon. As others reviews have mentioned description says pack of four but pricing is too low that it has to be only for one - assuming it to be a pack of ones I ordered four because my car needed four. For some reason my order was split in two separate orders and when package came in one box I received two four packs and two one packs (for a total of ten spark plugs). Reviews have gone back years and it seems it is still has not been resolved. it’s entirely possible you’ll receive the pack of four or a pack of ones. In my case I got both types of packs for a total of ten plugs. What a hassle having to return them.

Working well
These have different numbers on them and a different character on the spark plug head then the originals that are removed. However, they look physically identical and operate with slight improvement in lines of that of fresh spark plugs.
