My filter for my 2008 doesn't fit my 2011 car.

OP, the main difference is some are cotton filters (you can wash them), and some are are paper filters without the charcoal layer. Supposedly, the charcoal free ones are used in Europe.

The filter is the same size, except for a nipple at the top on 2010+ filters.

The 2008-2009 filters have a charcoal filter which is really restrictive. That's why swapping these older filters is much more beneficial.
