I was trying to take off the upper portion of my air box. E46. I released the three locks. Are there screws that need to come off to get this thing out? I couldn't get it to budge.

Wink I Hear Ya

Now, now... I promised my brothers of the Roundel that I would not speed any longer.

But... Being curious as a cat or like curious George, I took out the BMW standard filter but I left the charcol filter in place and I have driven the car for a few day to see if there are any differences in the normal drive.

The answer is, yes. Reset the fuel counter and I drove my normal city speed (35MPH) and average highway speed (80MPH). The result for personal view is 2.1MPG from 19.1 to 21.2 on average. I believe their is less hesitation from my gear shifts 1 & 2.

IMO the car can now take BIG gulps of air to what it wishes. I will place the K&N filter when I get it next week (Monday or Tuesday).

The "upper" filter is known as the "charcoal filter". It is held in with clips and just pops out.

Take a look at the third pic in the original post. If you cannot get your hand through the intake hole and push from behind on the 650 then another method is to just pinch the filter elements and pull until the filter pops out. This will probably destroy the filter.

You could also try prying the filter out using a small screwdriver on the outer edges of the filter frame.

Once the filter is out remove the metal clips that held it in place since you don't want those coming loose and getting caught in the lower filter.

The charcoal filter is a North America only part. It's put there for emission reasons (catches fumes leaking from engine after it's shut off) so there is no issue removing it. It is supposed to give a slight increase in power or at least an improvement in throttle response once removed so I would try it. Let us know if you notice a difference.

I don't think you can order a new filter if you break it though, I do not see it listed as an individual part. Not a big deal.

I'm a little confused by this...Is the "upper" filter the same thing as the rectangular charcoal microfilter (not pictured in this thread) in the upper rear of the engine compartment, under the windscreen?

No, this is a charcoal filter that resides in the upper half of the intake cover on all North American BMW intakes. It's there for emission reasons. You can see it in picture 3 and 4 in the original post. In addition to the charcoal filter you have a standard replaceable filter element that does the bulk of the cleaning of the air.

Do you guys think the charcoal filter is there for added filtering? Would removing it loose the 2nd protection to the engine?

Charcoal filter is there for emissions only. It captures any vapors coming from the engine after you shut it off. The Euro cars do not come with the charcoal filter so that should be enough evidence that it's safe to remove.

I would pull it out if you are in there changing the main element.
