I've heard that the SF's don't come with a Cabin Air Filter. Have somebody install one of these on a SF or would somebody recommend doing so?
They do come with a Cabin Air Filter. Its located in the back of the glove compartment.
My former '02 SF did NOT come with the cabin filter, much to my surprise! I did install one once I noticed that the slot was empty. Didn't really notice much of a difference but since I spent so much time in that car I figured it was important to have decent airflow in the cabin.
I now have a 2010 SF and haven't yet checked if there is a cabin filter installed in it. The dealership says there should be one.
