I found this when checking my air filter today. I lifted the top lid and noticed there is another thin filter stuck to it. It looks like it snaps in but it's kinda tight. I figure this needs replacing too??? Can I get this at the dealer or should I just take it off and let the regular filter do it's job. My '01 didn't have this. Anyone have any insight????
Charcoal filter for gas vapor in intake plenum after shutdown. Some have removed it, I would think it would very slightly increase airflow @ WOT. As with ALL emission equipment it is not legal to tamper, remove, render inoperative, so keep quiet.
