Mate, if you ask Dave, I'm pretty sure he has fitted one to his, I can't remember if he had to do any additional mods. Check out his Nav build up, it's on there.
From all the information i read, you need the YD25 snorkel, YD25 air inlet duct. By using these the precleaner will dissapear and you will need to drill a hole in the new air inlet duct for the air flow sensor.
Other then that, it should fit up fine.
I bought my parts from Gary at Nizzbits, should be here late this week of next. I'd say the price i got it all for you wont find cheaper.
