Great spark plug
NGK claims you will get more horsepower with these plugs. I dont know if thats true, but my bike starts right up now with no hesitation.

Very Good Plugs
My original plugs were 9 years old and I thought it was time to change them. It just seemed that sometimes the the motor did not fire up as quickly as I remembered. My wife and I ride alone most of the time and I need to know that she will start no matter how cold it gets. There is no pull cord, just a battery so no need to waste energy on extra starter power. These are original equipment plugs in my 660 turbo touring snowmobile and I trust them.
