+1. yeah the mesh is there for a reason...I would leave it alone. almost all cars that run a MAF have some sort of a screen to protect the sensor.

I thought that is what the air filter is for... Is there empiracle evidence to prove that it will hurt the MAF and hurt your performance. I am not saying that you guys are wrong. I just thought that the mesh is like an air-flow inhibitor and it just makes sense to remove anything that inhibits the free flow of air to the engine. Dunno...

In my uneducated opinion, the mesh helps minimize the turbulence coming in from the filter. Like anything else, the BMW engineers didn't put it there for the fun of it.

Here is my advice. I have first hand used the MAF cleaning spray from cnc and it works wonders. The car is fast and really responsive. I used it on my Nissan 240sx which had a MAF sensor gunk'd up with burnt off oil particles from my leaking charcoal canister. I actually got stranded on the road cause the MAF failed to work(scary). Later on I took my MAF off sprayed it down cleaned everywhere and put it back in. It was a Night and Day difference. You can't go wrong with it.
