Yes, descreening the MAF will help alot with the air flow, PERIOD!!!!!!!

A "seat-in-the-pants" feel from the power gian? I's not like switching from stock exhaust manifolds to long tube headers or somethintg.
I doubt there will be very little noticeable different. But that with all the ofther free mods and other little things add's up!

BOTTOM LINE IS: The air filter will catch everything, but what MIGHT get past the air filter is your own fault, case closed.

But it does help to descreen it, and add all of them other mods...like the free ram air mod, ERG mod, or any air improvements, now you're your getting somewhere.

And for you guys saying leave it:

Take a look at this pic:



Are you seriously going to tell me that it's striaght through, look at thet pic with the stock accordion sitting there, which will have the air bounce around and cause alot of turbulence before it hits the manifold where it'll split again for it to get to each cylinder.

Peace,
CRaig.

I think that the arguement is that of a straight shot BEFORE the MAF, which eliminates the need for the screen. After the MAF is of little consequence as the flow has already been measured. Either way, I agree with what you are saying...

I see what you are saying. Plenty of people have been running without one, and the C5 ZO6's didn't even come with one, and my 85mm Granatelli MAF didn't have one as well. Shows (to me atleast) that the screen is garabege and useless, no need for it, pop it out and throw it away. lol

I installed ported ends with no screen, did the PCM reset and got no codes. When I got it dyno-tuned later after headers, there were no stored codes at all.

Exactly why I didn't remove mine. It isn't worth the one horse you may gain.

Mine was coming apart, when the foam gets older the glue dries out and it comes apart. I just glued mine back on with some ultra black the other day.

They originally put the maf screen on the lt1's due to the fact that the intake came from the front driver side and hooked into the maf. Since the ls1 intake is directly in front of the maf the air is already coming in straight so there is no need to straighten it out more. I descreened mine and have never had a problem. Just make sure the seal is tight

I should mention what I did, which seems great.

I measured that black gasket thing and went to home depot to find a nice soft weather strip twice as wide and twice as thick. I found some 10 year rated stuff that has like 4 lips and holes cored through it for compression. Very plush for a great seal, but tough with it's 10 year rating. Also looks great when it's apart, as the gasket is a nice off-white, almost silvery.

Also, the box under the filter fit the filter terribly, as it looked like the front of the box sat too far forward, leaving a gap for the filter to fall into a little. As ghetto as it sounds, what I did under there worked perfect, I took a strip of about 3/8" thick wood and cut it to length the inside width of the air box, and ripped it to be the right height, so on edge with the flat mill edge supporting under the filter, fit's perfect between the box inside and underside of the filter edge, finally holding the filter straight where it used to sag some in the middle for a terrible "seal". Now the seal is quite overkill, which is good. Someday I'll spray the wood black maybe...

I descreened mine and it messed with some stuff in the tune. My tuner straightened out all the tables and it made quite a difference. But I ran it untuned for 2 years with no problems at all. I say de-screen em.
