On my A4 TDI, I've blocked underneath the valance - so that between the ground and the intercooler, there's not as nice a place to empty out the air that rushes through -- but I've kept that front grill closed.

I would like to figure out a better way - ducting the air out into the fender, perhaps (I'm missing side skirts yet, so intercooler air probably exits out there, but that cavity down by the intercooler is quite big.

A question, since I haven't seen an A3 engine under the hood - where does that model pick up it's air from the front? On my A4, it's on the upper corner of the upper grille.

I was thinking about that when looking at Sayyad's taped upper grill block: About 1/4 of the A4 upper grill feeds the air intake, so when I get to making a block, I won't be blocking that.
Current mod: Skidplate/Undertray for my MkIV Jetta. Next mod: CAD drawing for skidplate so other Jetta/Golf drivers can make one too!
