Will this work on a predator 212?

No, they do not fit that model.

Is this pack of 1 or 4?

These are sold in packs of 4. So if you need a total of 8 spark plugs, add a quantity of 2 to your cart.

Are these the same as ar3910x?

The 3933 is the standard and the 3910 is the power tip. Not sure what the difference is. They are the same heat range.
