Is this instead of having a hose going all the way down through the engine compartment to the ground, or is it in series WITH that ugly looking hose that then deposits onto the ground? Just curious. I found a little K&N cone looking filter for the valve cover at a VW shop for $10.00 Don't know if that is a good price, but at least I could see before I bought. VW shops are a great place to get little oddball stuff at good prices.
