Nothing, don't put anything in there.

That system was designed for cold regions. It's a small little reservoir that you were supposed to fill with coolant. On very very cold days, when you turn the key to ON it injects the coolant into the intake to boost compression. On warm days it does nothing.

It doesn't work, wasn't really necessary, and Mazda themselves issued a service bulletin to their dealers to remove it later in the production run.

You can safely ignore it. Many people block off the port on the intake that it connects to and remove it (myself included), but you don't actually have to do anything with it.

 

wow man thanks for all the info I really appreciate your time to explain me this, went i see it empty i get really worried about it
