For all the people who have bought the MotorDyne 5/16 ISO spacer, Did it come with one or two gasket(I'm guessing it is the gray or black paper thin spacer shape thing in this picture that is right underneath the spacer):

Just curious since performance nissan has a note saying:
"NOTE: Extra upper plenum gaskets are recomended, (a total of two). One upper plenum gasket will need to have the center cut out, to match the spacer. Please select below for extra gaskets."

I'm curious why it would be recommended to have an extra one, is it to prevent leaks? And doesn't our stock plenum sit on a gasket already? Or could I be all wrong and they are really describing the thing in the middle with the 6 huge holes in them?

The gasket with the 6 fat holes is the Iso-Thermal Gasket. If you don’t buy one, don’t worry about it. Between the OEM upper and lower plenum is a gasket: reuse it. The kit comes with a gasket. That makes 2: one for each side of the spacer.
