Air Box White Mesh (?) After Air Filter, What's Its Function?

There's a white mesh something after the air filter on my 1GRFE V-6 engine in my PreRunner, dealer says not replaceable during normal maintenance, in other words it's an integral part of the plastic air box and the entire air box would need to be replaced to change out this white mesh thing; after 220K miles it might need to be replaced, any idea what this is? Seems like it would restrict air flow after the air filter - - Thanks

 

It’s supposedly for air stabilization. Just blow it out, it’s not restricting anything.

to replace it you would need the whole air cleaner assembly.

 

It should never really get dirty if you are running a good quality filter in there anyway, right?

 

I believe it’s a charcoal filter to prevent fumes from coming out the intake. I drilled mine out shortly after knowing about it as I didn’t see anything good coming from it from a performance standpoint.

 

Leave it be.

I'm sure the engineers who designed the air intake were able to account for any "restrictions" caused by that piece.

It is there for a specific purpose. It controls fuel vapor escaping when the engine is off. Any vapor collected will be ingested when the engine is running.

You won't see an improvement in performance if you remove it.

But it is your truck, remove it if it troubles you.

 

Charcoal filter. Removing it has zero benefit.

 

How do you know this?

 

Because this gets asked probably once a week and it’s the same answer every time.

 

Barely 30 minutes after you posted...proof your statement is true.

This.

ALSO. If you are in CA and remove it for whatever reason, if you have a competent SMOG guy you will FAIL smog due to it missing.

 

Im not watching this forum like its my life. Some people

 

I must have missed it

 

Neither do I. But I'm also intelligent enough to search the forum first if I need to, before starting new threads. Some people

 

You are one smart cookie!
Do I search for a 2nd air filter thinga majiggy

 

Have a neighbour with a ‘10 Tacoma who swore he got better mileage without the white mesh (charcoal) filter. Did the same with my old ‘05 Tacoma and he was right - no other modifications and an immediate 50kms more per tank.
