In itself no, the later 182's had much improved inlets over 172 and early 182, although when Ben did mine he still removed a lot of metal. In conjunction with a live remap, maybe.
complete waste of money. I was charged over £100 and when I asked how much metal was removed I was told very little as these engines don't really need it done in the first place.
As this was part of an exhaust and induction change with remap I can't tell you how much difference it made.
