K&N Panel Filter - (33-2850 is the model number I think) - I found this gave me a little more in the low low revs and gives it a little growl at 2000rpm +. Thats about it really, you can opt to get a custom exhaust made, what ever you do you aren't going to gain anymore than a 10BHp at the very very most - that includes getting a re-map (£200), a custom exhaust (£400 ?), Induction kit (£40).. meaning you could easy spend £600 - £700 and gain very very little.
Someone that I know costantly complained of his 1.2 and it's lack of power went and bought FR 130 Tdi and wrote it off after 7 - 8 weeks after getting it as in my opinion didn't know
how to handle the massive difference in power...
Having driven 2 different versions of the 1.4
Ibiza I reckon the 1.2 maybe has a slight margin over it as all 3 versions of the 1.4 are quick sluggish lumps... this is just my opinion...
