It doesn't have a "gasket" in the sense of a paper gasket, but instead, it has a rubber o-ring.
I'm not sure if they are confusing that with what you are referring to.
If you look below, I attached the directions for the removal and replacement of the MAF sensor. It indicates there should be an o-ring. Otherwise, there would be an air leak, and the MAF signal would be off.
Keep in mind, the o-ring is likely to stay in the air intake box. Maybe because of that, most new ones don't come with a new o-ring.
The best thing to do is remove your sensor and see if there is one on the MAF or if it is part of the air intake box.
I attached the directions below for you if needed.
Let me know what you find or if you have other questions.
