Does anyone have an photo of the nc intake manifold?
I am building a race car and dice taking delivery I have noticed it sucking air through a small hole that I think a vacuum line attaches to?
Under the main engine cover in the plastic intake manifold, would only take a small hose.
Not sure what this attaches to.
I have removed the rest of the stock intake system from the throttle body forward and don't remember pulling a hose off it.

And ideas? Currently I have just got a small bolt in it to plug it up

Sorry I can't connect to your drop box. Does this help?

Do these help? Gee, I gotta clean that dust off before the next concours .




The screw drivers in the photos below is pointing to a tube that looks like it connects somewhere behind the black thing on the annodised bracket and then seems to go with another tube to the rear of the engine...and then??

The hose to the right of the disconnected red faced plug?



Which is the tube that sits hidden behind the plug (above) in the bottom right of this photo.

thanks JBT, your top photo shows that I am missing something.
Now to find out what it is!!!

Actually I think you are onto something with that.
Where do those hoses go??

"the black thing on the annodised bracket" seems to be the Variable Intake Air Solenoid Valve and the PCV valve is also nearby.

Read this and it may help you find where it used to go: http://www.mellens.net/mazda/Mazda-Miata-2006-2007/intake_air.pdf
