Plenum spacer?

[Tomgee987]

Hi recently purchased a 350z and I'm now looking into getting it mapped, it currently has a ash mushroom air filter, modified exhaust system but I was wondering is there any way of telling if it has a plenum spacer fitted at all? It's a 2003 import just like to know if there is any measurements i can take or visual clues to tell if it has one? Sorry if this been asked before or a novice question! New to the world of z's! Thanks, Tom.

Hi Tom

 

You can look at the side of the plenum it's self where the two halfs join if it loooks like this
