I got these for my 1996 Kawasaki KX60 2 stroke dirt bike. After running the stock NGK spark plugs for a while. Then the NGK Iridium, they were better at burning up any oil.
Then I did some research and found out these plugs fit. So I bought a four pack to try them out and I can say I am impressed they work fantastic! Good clean burn from these plugs. So far I'm very happy with them.
