I'm trying to make my own large bore MAF. If anyone out there has the range rover maf tube lying around I was wondering if you could take a few measurements for me. I need the measurement of the outside diameter of the tube, and the measurement from the flat where the sensor will sit to the opposite side of the outside diameter of the tube.

I have provided a drawing. Left side is stock, right side is what I am trying to make. In this case I have a value of 4.01 for the measurement I need. It is not 4.01 as the sensor will not fit.

Thanks in advance

 

anybody?
