: How many screens are there?

There are two, one in front of the MAF, one in back.
where are they and how do you take them out?

All you need is a flat screwdriver. Take off the clamp in front of the MAF and in the back. BTW, the MAF is the black unit in the tubing that is just before the airbox. There are a clip that is very easily removed and the screens just comes right out.
Can you put it back easily if need be, or do you need to cut it out?

That is what is so funny, with GM you ahve to cut them out. these you can take out and put back in very easily. I was very surprised it was that easy. Maybe the BMW engineers were thing ahead.

What are they there for if serving no purpose?

Folks at GM say they are to smothen airflow accross the sensor. Phewy! They take up so much space that the extra air going to the motor is more beneficial that the supposed straight airflow. And like I said, these are big poastic pieces, Vette, Z-28 & Impala SS are a thin wire mesh.

Just an extra precaution I would guess, so that nothing gets sucked into the engine.

That is the common percetion, but no way can something that big get by the filter.

: Thanks for helping.

Sure, let us know. I am heading out know so I won't be able to answer more questions till later on tonight.
Have fun. DOn't be scared, it's easy.

: : Take those screens out boys! Like I said on my earlier post, those screens are way more restrictive than the GM screens and GM's are worth 5hp at the wheels, proven many times. No check engine light will come on, and I could feel more power. You guys tell me. Just like GM, it is a 5 minute, free mod, and there is power there. You will see how restrictive the screens are, especially the front one, when you take them out. I put on a cone filter instead of the airbox and am feeling way more power, I think most of it is due to the MAf screens.
: : Again, let me and the rest of the group know if it IS the screens, or my new cone filter. Hope this helps.
