Hi Guys,
been doing a bit of a search about on here and keep coming across the air box mod(ie drilling extra holes and smoothing fins inside box + performance panel filter) is this the far best thing to do as ive heard induction kits on tdi`s are not really worth it? mine is the mrk 1 cupra tdi 150 who has done it and did you notice any diffrence ect ect....
cheers
