I keep seeing guys on here who take out the honycomb screen on their mass airflow sensor. Does it really do anything? Doesn't seem like it would restrict much air to me. But what do I know.... Any help would be great.

Can't say it would do much for a stocker but if you've got mods and need the extra air it should help.

NO. dont do it, itll just screw up your computer. this is one of those dumb-ass mods that just messes your truck up. the screen is there for a reason, actually more than one, but just leave the MAF alone.

Its gonna scew up the computer huh. How do you know this???

Some pepole have to lay off the forum reading and actually have real world experiance to back up what they are saying.

That being said, I know of many trucks and cars that have run without a screen for many years no codes, no troubles, no changes in fuel economy and last but not least no extra power.

On some of the newer 3.8's and such you have to remove the screen just to clean the TB blade. Nothin bad happens when you do that either even 100k down the road.

The screen is there to straighten the airflow as the air passes over the MAF sensing element.
When you pull air thru a passageway it causes the air to swirl around. The MAF measures the airflow by sensing the degree of cooldown of a heated element. If the air swirls, it fools the sensor and causes the computer to measure incorrectly.

Removing the screen won't damage anything, but the engine will run better OVERALL with it in place. Expecially at idle and just above idle.
You can gain almost no airflow improvment by removing it. Better to leave it in place.

Is there a way to get a screen back in there? I bought my truck and it was already gone.

We used to remove all the screens on our LT1 Z's. But that was for a good reason. LT1's were made to run SO rich it was nutz. By removing the screen it leaned it out and actually ran better. It's not necessary on these things at all....late...

i removed mine and can't tell a difference at all. it may run a little worse but i have enough other crap to override that. no codes or anything though.

Thanks alot guys...thankfully mine just popped right out, and popped right back in. I guess i'll leave it in. Really doubt it would help much anyway.

asses...yes, i read enough posts to judge that removing the MAF screen does nothing, and in some cases, will cause the engine to run worse and throw codes. sorry i cant afford a ****ing Blazer right now....cocksuckers.

please explain muddy s10. i've gotta hear this.


btw, is this from a super altima experience?
Why don't you stick your sarcastic attitude up your ass along with your head.

He owned a 4.3L and through reading, he sees what most people are saying.

It's common knowledge the descreening MAF sensors is know to cause problems on some engines, and others it makes no difference.

Very True, he is always trying to help. Even though we don't all personally go through EVERY problem, we see what everyone else is saying and we remember.

for this one, if you think all my experience is in cpi's, you're way off. some of us here know a bit more about cars than what they've read on forums. i don't need the backing, but i'm sure many will back what i know.

so, what's your challenge?

You are an arrogant ass.

Please, you say you know about this, so let's have it? Lay it out, WHAT DO YOU KNOW?!

Let's see how someone owning a vehicle that doesn't have a MAF can have SO much more thoughtful arrogant sarcastic childish comments?

BRING IT BRO, YOU PICK ON MUDD, YOU GOT ME TO TANGLE WITH TOO.
