that matt would be me, yeah i think u get a bit of extra performance but hardly anything, and to be honest its probably psychological anyway cos everyone seems to expect to get a gain from an induction kit, the noise is alot better thou, but like ryan said we ended up stickin a green filter on because with the piper-x filter there aint much of a sound, more of a scream i found, but u gotta buy the piper-x one to get the plate to go where ur original air box is, fortunately my mate was willing to give me his green cone for my piper-x one, my mpg aint suffered much at all, is at the moment, but thats only because there is like one road open as all the others are closed near me for floodin, so its permenant traffic jams, which is buggering my mpg alot.
