I've found out my fren 4AFE inlet manifold is quite different from my 7A inlet manifold. What you think there is any different in performance? He said his runner port is bigger thn mine.

it looks like you are comparing AE10X 7AFE with AE11X 4AFE.
if you compare AE10X 7A with 4A in same chassis it will be very similar/same manifold (as in 2 part).

my ae101 4afe inlet manifold is the same as the lower picture

so is there any diff in terms of performance on both design?
