Thanks all will be ordering it tonight, i actually found it cheaper if u go directly on to there website GermanAutoSpares and not though ebay its 29pound but i haven't looked up the delivery yet.
I'll done a lot of research in to either revision G or D and chose to go with the G, I'm hoping to get her booked to to have eibach sport line springs fitted and while he was there though I may as well get the precat removed and replace the Diverter Valve too. Then hopefully a remap later on in the year.
A Diverter Valve is directly on ko3 turbos on the standard GTIs and it stops pressure being pushed into the engine/turbo when you take your foot off the accelerator so you don't cause problems it also holds the pressure at WOT and accelerating
Im sure some one will add more or correct me
