Secondary engine air filter?

[Heavytech]

Hi everyone,
I was checking out my engine air filter today to check if it needed to be replaced, and I inspected the air intake tube and housing while I was at it. I noticed on the engine side of the filter housing, so the top half, there was what looked like this white secondary filter, almost like little pouches stuck to the top side of the housing. Is this a secondary filter, or a primary filter failure indicator?
What concerns me is that it's dirty looking. Im a heavy equipment mechanic myself, and if a secondary air filter is dirty on a machine, in generally means that the primary has a puncture or some other defect. I can take a picture if need be, forgot to do so while I was in there. Any insight?

Thats the carbon packet for emissions...non sure why it would be dirty...but I ripped mine out..figured it was another air restriction. I can see how a regular paper filter could be punctured...did you look at the air filter for damage?

It's a sound reducer and condensation pad.

Ah okay, yeah filter itself looks fine, Just havent seen this carbon packet before. I work with diesel machinery so that stuff doesnt really exist. Thanks for the information

Sorry where is this part? I think I heard restriction which means must be removed.

haha, if you remove the top of the air filter housing and then look at the part going to the engine, you will find this packet/filter stuck to the top of the air filter housing.

I bought an Injen SP7035BLK Air Intake System. Do you have ANY tips on removin said emissions equipment? I live in a state that does NOT require emission inspections. I'd appreciate the advice.


I have an entire separate tubing system coming out of my stock air filter that's not in the Chevy Owner's Manual at all?

It's not necessarily for emissions - it's carbon to reduce the smell of raw gas that may be left in the intake tract from the fuel tank ventilation system. It doesn't hurt anything.

I installed the air intake, and I bypassed the Secondary Air System with a tiny air filter
