sorry, ID=inner diameter
what is the ID of the maf tube itself?
also, is there any screens installed, like the stock one has?

 

I'm pretty sure its 3".. the entire tube. its plastic. but still its for wind.

 

I just thought of something, did you cap of the VFAD?

 

^^You beat me to it!

 

honestly i have no idea what the VFAD is. variable fresh air duct or something? no idea where it is though.

 

yup, you are correct

 

lol.

 

Also... did that intake come with any screens to install.
The AEM has them to straighten the airflow and reduce turbulence across the MAF sensor.
I don't think the MAF would like it if there were no screens installed.

 

where is it?? lol i have no idea what it looks like or what it is. whats it do?

 

and no it did not come with any screens. its a tube with the MAF just sticking in there.

 

anyone have a pic or description of the VFAD?

 

Here is where the VFAD nipple needs to be capped.
Keep in mine my intake manifold extension is upside-down in this pic.

 

3" ID is too small...the MAF will think there is much more airflow than it should...hence too much fuel...and extremely rich

 

you can use the screens from your stock intake probably to reduce turbulence

plug this if you didn't already, this is a pic swoope took:


edit: shoot you beat me this time Jon, lol

 

 

Maybe... but those screens are a PITA to remove without damaging it (had to for the Racing Beat intake) .

LOL

 

kk important question. Do you think the AEM gets me more gains or this? running too rich isn't good? why?

 

Everything looks connected to me...

 

honestly the stock airbox with the inner walls removed, k&n filter, plus racing beat air duct would be better...and cheaper. AEM looks nice though....and it will def. work better than what you have now. It is something made specifically for the RX8. Running too rich is making your car run like crap....when you floor it it stumbles. Too much fuel.

 

look at Jon's pic and the one I posted....it is underneath the intake behind the throttle body

 

it doesn't show in any of my pictures?

 

 

no.

 

Do the 4 port 2004 AT even have a Vfad???

 

yes.
