gsr are the best inductions u can get for the punto.
as for reasons why everyone rates the focus induction to an extent is simple, cheap to buy, easy to fit and does the job. it aint perfect and could do with a longer pipe to be able to move it away from the engine block/radiator, but for the price u cant complain. its just so happens that the focus kit fits perfect on the 8v engines.
and playboisoldier, i did my kit by removing the airbox, cutting the inlet pipe just before the bend, putting in a metal collar where the cut was made and twisted the end round away from the manifold then fitted the filter. aint fantastic as its still behind the radiator, but for the price of a cheap filter and a couple of jubilee clips, ur gunna be hard pushed to do it cheaper. when i get round to it, i will most likely extend the inlet with some ducting so i can place the filter behind the front bumper grille. just need to work out a way to keep the filter in place down there.
