Or you could head to your local parts store and buy the NGKs there, i know advance auto has them, and they should be in stock. If your looking for plugs for your atv, pull one out, head to the store with it and have them cross the number. As for O2 sensors, bosch tends to be popular and work well. I never had a problem with mine.
