Air filter cover. 2.5 L engine.

Any idea what is attached to the inside of the air filter cover?
I changed my first air filter today and noticed this.

Sound dampener?

Carbon filter perhaps??? Just a educated guess.
The Hybrid engine does not run all the time. It is a carbon filter to keep fumes from escaping??
One of the things they have to do with a hybrid? Like pressurizing the tank.

Whatever it is, I wonder if it is serviceable.
It is attached by a few rivets. Should I be concerned it might fall off and fly directly into my engine sooner or later ? Will it be a good idea to take it off once the warranty expires?

"The intake air system provides clean air to the engine, optimizes airflow, and reduces unwanted induction noise. The intake air system consists of an air cleaner assembly, resonator assemblies, and hoses. Some vehicles use a hydrocarbon filter trap to help reduce emissions by preventing fuel vapor from escaping into the atmosphere from the intake when the engine is OFF. It is typically located inside the intake air system. The hydrocarbon trap is part of the EVAP system."

Mine is the same. If you gently touch it it has beads inside. Similar idea to oxygen scavenger packets in some food packages. Fun fact: Dole pineapple and pineapple juice always comes in steel cans, not aluminum and generally not plastic. They want oxygen in the can to react with the iron in the steel and leave the juice alone. It's worked for 100 years.

Almost 30,000 miles on this filter: engine side:

Street side:

This puppy is still good.

Oddity: Tabs are "square" on the right:

But tabs are at an angle on the left.
Just be aware.

Which looks odd since from the outer case, they both look square.

I highly recommend you loosen one hose clamp on the throttle body. Takes 15 seconds and makes life so much easier and you can peek inside.

I think I will wait till the warranty expires. Then I will buy a new upper air filter housing and replace mine. I have not found a part number, but for 2020 Escape hybrid it is NZ6Z9G784A, LX6Z9G784A.
Then I think I will remove rivets and bags with beads, install the housing and see if the engine throws a code. If it is all good, I am driving with the one that has no bag with beads attached. The plan is to make it to 350K miles on this Maverick.

If anything, that additional filter will only help. Silica getting into motors via the air filter is a major cause of wear on engines, which is why cheapening out on air filters is a fools game.

My wife's Prius has an additional filter on it as well, it's 14 years old.

My 22 doesn't have that! Does it cover an access hole that a mouse uses to bring corn in occasionally?

Another reason to cut the bag with beads out?
The bag is riveted to the upper housing. It is past the engine air filter. That is why it concerns me so much.

Look again. It is on the top:lid.

The photo is inverted.

No holes. Air does not pass through it.
It is just an absorber of sorts.
Does seem "insignificant" to me but....

What if those gasoline soaked "beads" have great lubricating properties?

Ya just never know!
