The stock is honeycomb isnt it!? Most people take it off when they have a FMIC fitted though.
As ive already posted this in the Mk3 section, i thought i'd share it with everyone......I know it needs a clean and i need a new cupra badge but see what you think:
What diameter is that silicon hose from the tip to the Maf?
I guess the internal diameter will be 70mm as that's what size the MAF is.
