Ok, I might be getting confused if there's differences between S4 and S5, but I think in general they have similar setups.



Directly behind the air filter on the S4 is this metal piece thingy that the piping goes into. A sensor connects to that metal piece. Is that the AFM?



If that's the AFM, is the cone-style intake AFM only for S5?



Is that the only sensors/electronics involved for intake (past the TB I mean)?

as far as I know for n/a:

yes

yes (s4 has flapper door style)

yes
