Best Cabin filter for Volkswagen Passat

Since I was in the area, and needed to swap out the cabin air filter, I opted for one from K&N. I have upgraded to the B5.5 filter housing so that is why this should work. There is a slight length difference but it does fit.

I checked to make sure the cabin filter wasn't restricted (Mann filter less than a year old).

Purchased OEM VW Charcoal Lined Cabin Filter / Fresh Air Filter and OEM VW engine Air Filter for $40 from ECS Tuning. Installed at 102k miles.

Note that changing your cabin air filter could help too.
