Thought that mesh on the MAF was probably a bit of a restriction so I decided to remove it.
Common thought is that it's needed for some flow effect, but that dosen't seem to be the case. For one thing, it still works, the MAF voltages measured at idle and 2000,3000rpm, no load are the same. I also showed it to a guy who has worked on industrial ones for years and he said "It's a classic design and those are only for physical protection NO flow effect other than pressure drop"
Does feel a bit more responsive
hmm, was told that the mesh is there for flow reasons, & most bosch units in use now days have a very large mesh that would be no use whatsoever as physical protection

Posts: 10,660 I think the Aussie guys had a page on this and the concensus was that mesh removal did improve something or other. I actually bought a 2nd MAF just for this (like incase I bust mine) and so far all I've used it for is lending to people to confirm whether theirs is busted ...

Posts: 2,398 I took mine out as it was a bit damaged, and didn't want 3" of stainless wire falling into my turbo etc.
A guy with an S13 and a huge top mounted turbo had problems with turbulence at idle due to the AFM being so close to the turbo. He had to make a baffle to put between the turbo and AFM, all sorted now but mesh wouldn't have fixed that.
