### ⭐⭐⭐⭐⭐ Review
*by K***N on 22 February 2021*

I read a lot of stories saying there is a high chance to get a fake spark plugs if you're buying from Amazon and the likes. Got me somewhat worrying and curios, and so I went to an auto parts store and bought the same set of plugs. Guess what -- the set from the parts store is exactly the same as the one from Amazon. It looks exactly the same, all the dimensions are identical, the weight is the same, the resistance is the same. I have replaced a set which was installed 3 years ago and did 25000 miles on my Yamaha FJR1300, and it did not really need to be replaced.
