genuine
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.

I purchased BN 2016 Suzuki Burgman 650 in September 2016. Now, she has 14000 miles on the dash. Yes, it is time to replace the plugs. I considered 2 options; standard plugs (CR8) and Iridium (CR8EIX). My local auto part stores sells the standards for $10 a pop. Then, I see this set of 4 for a lot lower price/plug. I don't know much about IRIDIUM plugs but it helps my bike's idling and accelerating when underload.

Spark plugs were unusable
When I opened the spark plugs they were used and so were completely unusable as replacements.
