Inlet manifold help

[big_mo]

I have just brought a new but standered inlet manifold for my A3 (y) 1.8t and just wanted to know is worth having it ported and polised (inside only)?
If so can any body recomend someone that can do this for me?

In short no.

To elaborate a little, the inlet manifold isnt a restriction until you get into mid 300hp's so on a standard or even chipped car, you'll achieve nothing.
