A hydrocarbon absorbing filter, comprising:
- a media filter comprising a first end opposite a second end, an environment facing surface opposite a clean air facing surface, wherein the media filter defines a clean air passage;
- and
- an internal hydrocarbon absorbing element disposed within the clean air passage.
A hydrocarbon absorbing filter, comprising:
- a generally truncated cone media filter comprising a first end opposite a second end, an environment facing surface opposite a clean air facing surface, wherein the media filter defines a clean air passage;
- an inlet cap attached to the first end, the inlet cap having a cap exterior surface, an inner surface, and defining a recess in the inner surface;
- an outlet collar attached to the second end;
- and
- an internal hydrocarbon absorbing element disposed within the clean air passage.
