I have just seen this thread and il tell you guys that the 1.4 golfs aint that bad!
IMO best induction kit is the pipecross one, lovely sound towards higher revs.
Apart from obviously the filter, there arent that many things you can do; a chip will do next to nothing, I know because I had mine chipped when the 1.4 lump was in it :embarassed: Apart from that if you want to get a bit of speed is just do your cams and get a full straight through system which will increase air flow but to be honest if you got a 1.4 you aint gonna get much speed out of it, hence why I changed my lump - plus the fact that the gearboxes are weaker then a stoned 3 yr old, plus they cost a f**king bomb to replace as they are like gold dust!
