Hi,
I've got a plastic Autodelta intake kit, which by the look of it just looks like the original one off a v6.
Basically the new intake replaces the old one which is relatively restrictive and contains a load of baffles to keep it quiet.
Fitting both the intake and new filter to a 156 TS does increase the throttle response, makes it go a bit better and also increase intake noise (in a nice way).
I don't know if this can be done in the same way for a 2.0JTS.
Details of using the v6 intake are on
