Buying plugs for the new Superjet and wanted to know which one of these I needed and what the difference was both are B7HS but just not sure what the other numbers mean.

That's the one! Be sure to remove the aluminum thread on adapter on top, add some thread locker, and tighten it back down. And add some anti-seize to the threads for good measure, although the 2 stroke oil usually lubricates them well enough.

You got them for a great price including shipping!

As an alternative, there are solid top BR8HS available, NGK 6715. They are $2.11/ea on Rockauto, used to be $1.70...
