Stock Air Intake System Questions

[black2]

Hi,

Does anyone have the measurements to how many "inches of water" or negative PSI the standard intake system produces ??

Someone out there will know what I'm talking about I'm sure!

I am hoping its going to be around the 9-10 mark... but looking at the air intake system and all the corners it has to take im sure its going to be more like 20 !

Thanks!

Richard
