Where to mount Filter Gauge???

[FowerRunner]

I bought a Filter restriction gauge that mounts on the Air Box, just not sure exactly where to get best reading, seeing that I still also have that Carbon Filter deal still on the underside of the top part of the air box....Thank you in advance for any help :cheers:

GM has done this air filter restriction thing for a while, but I have never heard of a carbon fiber air filter set up. I would set it up after the filter.
