do these work, and if so are they worth the money? how much power increase, if any, can expect to get on my 1.3.:suspect:

cheers for that rich, i wont bother then, not really worth the money for me then, im only using a k&n replacement filter an a full exhaust system, i think cams will be my next move.

Kristian has one on his car, I'd say you get something if you do the other mods like 1.6TB and exhaust setup but kristian will be able to give a better answer.
