That is a a "carbon Trap" to minimize air polution.
It prevents gas vapors from backing up through the intake when parkred. It's held in place by plastic rivets. Some have taken it out with no apperent bad effects but, removing it is controversial as removing it does not really help performance to any noticeable degree. |
