Good question i'd also like to know

 

It is referring to a MAF (Mass Air Flow) sensor. The 5S-FE only has a MAP (Mass Air Pressure) sensor, not a MAF.

So in other words, it should be fine to use.

I think it's Manifold Air Pressure.

 

^ Manifold, Mass, same difference. It's still air pressure. lol

 

Agreed! A more generic term is thingamajig.
