cost
I got it trade, normal price is about £85 i think. I phoned up Pipercross direct when I spotted it in a Fast Car mag about 3 months ago in the new products section.
I got a mate who works at Fiat to fit it, a bit fiddly, but not difficult if you know your car...
The main thing is to remove a flap under the passenger side wheel arch, 4screws I think. The reason for that is that when you undo the original air filter, you can't pull it out from the top, so it comes out from the bottom thru the wheel arch. btw, don't remove your wheel , its not necessary, just turn full lock. Other thing to look out for is that you need to undo some piping to lossen everything, just make sre you tighten them back up.
The instructions should be good enough.
email me if you have problems
good luck
