Thanks David.

I feel a little sheepish, but did not realize that K&N filters used
oil in the filter element. I know that oil fouling the MAF is already
a potential issue with the stock Jetta 2.0 so wouldn't want to
possibly exacerbate that.

I know of two other VanaJetta guys who are using Honda (Model?) air
filter boxes. To my eye, they use larger elements (hard to tell from
these pics)

than the Caravan V6 box.

Actually I was quite surprised to see just how small the Caravan box
looked compared to the Jetta box.

I removed the silencer when I installed the box so the flow may be "ok".

I have to "Air Care" (emissions testing) my VanaJetta soon (crosses
fingers.....). Hopefully the Caravan air filter/box won't create
trouble in that regard.
