im not on about the origional box with a element filter in it. im on about a performance open cone filter. i agree its a better idea to go for the piper cams. but was wondering if it was a good idea to use the zt 190 cams that i can pick up for a few quid at the local scrappy ( they aparentally have a set there) or pay £500+ for piper cams. i would rather go for zt190 cams if the gain was similar bhp wise and save myself a lot of pennies. just wondered what benifits they would have on the zs 180 compared to piper cams. if the zt ones offered 10bhp and the piper offer 14 bhp i would go for the 190 cams and the outlay would be about £400 less
