Just got my 1.0 E! A friend of mine has a Mushroom style air filter lying around that he's offered me. What i wanna know is, am i gonna get any performance improvements? what'll happen to the noise? will it kill fuel? oh, and while im at it, this is my first car and everyone seems to be diggin the premium fuel (optimax, v power etc), are they worth the extra bread and why?
