You really can't beat these spark plugs. Work great and last a long time.

michael in VA
Great spark plugs. The only plug I use. I change once a year for trail riding. Never fouled one
Dallin in UT
Original equipment for my Yamaha's and Honda's. Is there any reason not to use NGK? Works great for my stock bikes and quads, no sense in changing it for some other brand.
BRIAN in MA
i usually replace my spark plug before every season. i just chose this one cause its the same as stock
Dustin in LA
By far the best spark plugs on the market
