Of course, "worth the time" is totally subjective. To me, a pointless mod is not worth even 5 minutes. Obviously you disagree.

But if you'd rather resort to ad hominems, be my guest. It just shows that this conversation, like the charcoal filter delete, is also pointless.
Your over usage of the word "pointless" solidifies your incompetence to make a valid argument. Therefore, I will not waste my time with yet another Holier-than-thou 1 Series owner.

Happy motoring.

It seriously took me no more than 30 minutes. Almost all of that time was unscrewing, rescrewing, and rubbing sand paper on it. A monkey could do this.

As far as a difference goes, I don't know. Nor do I care. I enjoy messing with these things, so why the hell not?

I've got 1 year of warranty left and I'm torn between this mod or the eurobox when the warranty is done.

I used the word exactly thrice. Twice to describe the mod, and once to describe this conversation. Doing so was a deliberate attempt to tie the two together. I'm sorry you didn't catch that.

As far as any valid argument, again, I reference my 1st post. I think it's fairly well-reasoned, and that I explained myself rather clearly and logically. My whole "point" (get it?) in posting was to generate some sort of rational discourse on the topic.

It's puzzling that someone whose most compelling argument thus far relates to "sandy vajayjays" would have any room to criticize the ability of others to make valid arguments. I guess it's true what all of us 1 Series owners think about E90Post.

from what i read... OP started this thread because he/she was some what interested in this mod. i guess its just that OP cant decide whether or not can/should/would do it or just leave it alone. but just the fact of knowing of a such mod exists gives that itch... and started this thread to at least see what others are saying or doing about it.

its ok if you do not want to do this... and if you do well you wont have any questions about it afterwards.

but in all honesty... really really really.... really simple mod. you cant go wrong... unless your just a person that everything goes wrong when you touch something.

there is no words to describe this mod or any mods to 100% just got to take people's words for it... this is almost like a "beginners" mod so there is a lot of threads about this... please search and read to the fullest.

if you cant... then just suck it up and do it or forget about it.

In the time you have taken bitterly arguing a mod that most people do just for the fun of tinkering on their cars, you could have done 4 carbon filter deletes. hahaha... lighten up bob.

And to contribute to the thread: I'd honestly spend the extra $$ on the Eurobox + K&N filter. Keeps the stock intake in one(well... 2) piece(s) for future convenience, easier to replace filter, and IIRC, cone filters(EU) are better in terms of performance.

ECS Tuning has both the Eurobox and K&N filter for about $450 shipped:

I did upgrade the intake, but with an M3.

When I replaced the stock air intake on my 128 with the BMW performance intake, I also did the carbon filter delete. The result of the two was a noticeable improvement in throttle response. Given the consistency of the charcoal filter it seems logical that it's removal played a significant part in the throttle response improvement.

I recently removed the charcoal filter and added K&N filter. It took 1/2 hour and was fun to do. I love little projects like this weather the performance changes or not. For me it is enjoyable to work on my car and put my own personal touches on it. I do hear a nice new noise from the engine, not a growl like a cone filter but its there and the car pulls a little better now. So in conclusion i'm glad I did this mod.

I definitely have a highway mpg increase, around .1.5 mpg. Power increase is maybe. I'd do it again just for the mpg.
Most of the criticism here is healthy skepticism, but most of it could also be leveled at other intake mods. This one costs 100s less to try.

I mean if they go through the trouble of opening the airbox...more power to them haha

there is no way to tell just looking at the airbox. They would have to open it up and have knowledge of an N52 airbox

If you are going to spend the time to replace your filter, removing the charcoal filter is not going to take that much extra time.

My 2011 E91 is a June 2010 build. Last week, I decided to replace the air filter with one that I had ordered from Amazon.de. When I pulled the filter, the date was June 2010—it was original. All things considered, it was in decent shape.

Anyway, while I had the air box off, I decided to clean it with soap and water. So I removed the air flow meter. I then realized that the charcoal element probably should not get wet. It also felt cheap and brittle, so I ripped it out. As it was glued in place, I removed the residual glue and material with a small paint scrapper, then sanded the area where the glue was with a medium grit sandpaper. In total, this took about 10 minutes (and looks factory).

I then washed all components with warm, soapy water. After drying, the airflow meter went back in, then the new air filter.

Have I noticed a difference? Not really. Sound and MPG are the same. And I have not gained 1000HP. That said, I am happy to have that brittle, after-thought charcoal filter out of my car.
