Big and Little Mystery Boxes Under Spare Tire

[Atlanta_man]

Big one is probably emissions / pollution related

The first box is a dust filter for the fresh air intake on the charcoal canister (second box).

Think it's serviceable? Would it be worth cleaning every 100k miles or so?

 

[Acidmeld]

Serviceable, no. Replaceable, yes. Not really worth it tho. They very rarely fail.

your underside looks very clean, no rust.
