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.

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

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

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.
