mesh on intake manifold??

[LuisPRTRD]

can I remove the mesh that the intake manifold has? some one told me it can help to get a littel more air in the engine for me this it can't be true the mesh dosn't look that restrictive :iono:

I believe its purpose is to "straighten" the air flow to the MAF sensor. If you remove it you main gain a small amount of additional flow, but it may also cause issues with the MAF.

[TOLMACH]

Isn't this after the MAF sensor?

[WeeYari]

^ Yes it is. What is shown is the throttle body gasket. From any information I've been able to find, I think it's purpose is to reduce turbulence into the manifold.

OK. Apparently too much wine for me tonight.

Aha! So he IS mortal!

To the OP: there's a carbon filter in the top half of the air filter box. Removing it may slightly improve performance, but will likely cause issues with warranty and emissions testing. Proceed at your own peril. =)

That said, not having it in place lets you hear the air moving through your airbox much better, but isn't quite as significant of an improvement as installing a CAI or drop-in high-flow filter.

I already have a CAI :thumbup:

so if i remove the mesh I might get a check engine light? me no like check engine light hehe

^ ignore what Scott had said. He was in error when looking at your picture. What you have shown will have nothing to do with the MAF.

[LuisPRTRD]

oh yeah to much wine haha I might remove it to see what happens what I thinking is that I my get some rough idle because of more air turbulence but as long as the check egine light stays off I'm good

[WeeYari]

I don't know if you can remove it without destroying, or at least running the risk of destroying the rubber gasket itself.

Less turbulence = more air, so removing the mesh may actually reduce your air going in, not increase it.

[LuisPRTRD]

aaah ok thanks

Exactly. For some reason I was picturing it on the other side of the MAF.

It would be easy to remove as you would just have to snip the four metal tabs where it is bonded to the rubber. A replacement gasket is only about $6, so it would not be an expensive experiment to try eliminating it.

To scientifically see its effect, you could watch the MAF data (relative to throttle position and RPM) with a scan tool. If you see an increase in the MAF parameter (which measures air flow in 100 grams/second increments) for the same RPM/Throttle position, then the effect of removing it is positive. If the MAF value decreases, then the turbulence do indeed effect the air intake and the effect of removing it is negative.
