Were you eyeballing those numbers? Unless you are just reffering to the turbo inlet
elbo for the turbo side and MAF piping side?
Stock MAF Pipe at connector = 76mm (2.99") ID with 82mm (3.23") OD
Stock MAF at Sensor = 72mm (2.83") ID
I don't have my stock intake piping handy at the moment but likely it's 3" ID on the MAF side and and possibly slightly smaller on the turbo end once clamped down. I sold my stock turbo so don't have the stock turbo inlet numbers either but it's likely 3" OD and less than that for ID due to the thickness of the aluminum intake elbo. I'm sure someone has these handy off the car somewhere they can measure.
Many aftermarket Turbo intake pipes are 3" all the way through at the sensor and where it couples with the turbo so they tend to throw off airflow calibrations a bit despite only being 4mm larger diameter where it measures the airflow.
