i'm not really sure on this one since i'm not very familiar with those, but i think that the piece on the 2nd picture is supposed to have a filter in front of it... i suppose you can take it out since you don't have the filter on there anyways. so i don't see why you couldn't get rid of it... IMO

The piece you have identified in the second photo is simply an air deflector. It induces the intake air to flow around it to all areas of the filter, instead of just at the otherwise exposed portion just inside the snorkel. It prevents large debris, moisture, and excessive heat from the EFE system from getting directed at the filter element. You can remove it if you like, and the only consequences might be a really dirty spot on the otherwise clean filter element, and possible baking of the filter element seals in that area if you're still using the EFE.

It's a charcoal bed to absorb fuel vapors while the engine isn't running. When you start it up, the air flowing over it picks up the fuel molecules to burn in the normal combustion process.

Unless you're worried about them popping the lid during an emissions inspection, it can be removed.

The real question is, do you have any thing to gain or lose by removing it. It is there for a purpose. Need to figure that out first the reason it's there and then see if anyone has any solid proof that removing it will gain you anything. No other changes, removed on the dyno or the 1320. Same day same conditions, otherwise its comparing apples to oranges.
