997 standard vs. 997 x51 airbox vs. evoms

[Vman]

Does anyone know if the X51 intake is the same size where the MAF sensor sits as the stock 3.8 997 intake? Also, has anyone measured the depth of the MAF sensor protrusion.

I am asking as we are considering using an EVOMS intake and want to know how far off if at all the MAF reading would be due to the physicial differences in the intake diameter if any. Also, anyone who has upgraded from a standard 997 intake to a 997 X51 intake should know this answer as if the diameters are not the same they are going to be getting false MAF reading that could cause their car to run too lean or too rich, unless they have someone write a custom program to adjust the MAF reading for the physical difference in intake diameter.

Thanks,

I found out today that the intake at the point of the MAF sensor is the same inner diameter for 996/997 and 997 x51 intakes. The difference in the X51 intake is that the factory one has two air snorkels and a bigger internal diameter hose to deal with the bigger inner diameter of the X51 throttle body.

The MAF sensor on the stock 3.8L airbox and the X-51 are interchangable. I've done the conversion with no problems other than adapting the X-51 inlet hose to the stock inlet plenum. No errors, car runs great with the second inlet and X-51 airbox.
