Looks like you should add "charcoal filter delete" to your signature of mods!
If it's not too difficult to do, I'm planning on doing this over the next week. To those who are skeptical, just think what possible advantage there is for keeping the filter other than to reduce some gas fumes escaping thru the engine/valves. It has never been there before on the E46, and I see it's possible disadvantage as reduced air flow across an additional layer of filter material.
Anyone remember the clutch stop mod on the E46?
This charcoal filter delete looks like it'll be like that mod: very simple, cheap, but one of the most effective mods. :rocks:
