Title: TDI aftermarket CAI filter
Post by: dashworth on January 10, 2010, 01:13:05 pm: I know the GTI and other Mk5 engines are slightly different to the TDI OEM intake, Ive looked at some sites and I am very confused as to how I change the OEM box to an aftermarket jobbie...
Has anyone got any pictures of how they have changed their OEM boxes to aftermarket ones on a Mk5 TDI? or just some helpful advice would be apreciated thanks gents

But i am also tempted to get hold of a Carbonio intake and see if it will fit on my car for the eye candy if anything.
But when i was searching i did come across this

Which is a BMC CDA intake system wich is available from Demon Tweeks
