Question Inside Diameter of intakes
Ok I've searched and searced and still san't seem to find a straight answer.

Has anyone took the exact measurements of the "Inside Diameter" to the stock intake and MS/AEM intake?

This info would be much appreciated TIA!!!

I don't know about stock, but I think the AEM/Mazdaspeed is 3.5" because the FI guys can use it if they are using the cobb acessport

On the AEM intake:
The upper inlet pipe is 3.5
The lower inlet pipe is 3.25 for the air filter assembly

Either way it's far more airflow capability than the engine can ingest so hopefully you aren't thinking about making it larger.

Silly rotarygod, bigger is better and a 4.5" intake diameter would allow greater speeds to be reached at lower rpms.
