Sorry but I cant find a link ?

Anyone knows for a guide or location.

Thanx

It seems it is another thread that has gone missing during updates (much like the how to fit the 312mm brakes).

It is very easy to do as VW VRS says in another thread:

It's pretty much a matter of unclipping the existing pipe bit, then unclip the intake part (plastic bit near the radiator).

Once that's done, put the new one back together. IIRC it's got a screw near the airbox end, and it just kinda slides on/off the intake bit.
