I took out the charcoal filters out of my 2010 w212 E63 and noticed:

Car sounds louder from engine bay at high rpms (prob more air intake)

Feels like there is a delay in low end rpm response and increase in high rpm performance.

Transmission kicks harder in lower rpms.

Overall the car feels funky, and not in a good way.


DID I TAKE OUT THE WRONG ITEM?
I took out the gray filter on the top of my air box and left the orange ones in tact, so im assuming I did the right procedure for removing the charcoal filters. Has anyone noticed proven gains from removing them if not should i just get new clean ones and pop them back in?

You took out the correct ones. Dont think your going to feel an increase by the seat of your pants. A dyno will show a slight increase.

Your impression of less low-end torque feel but more "go" up top matches my experience when I had chrcoal delete and high flow filters. But I didn't notice any change of power delivery with just charcoal delete. Of course, I had a de-tuned m156 and smaller diameter exhaust in my C63 compared to your E63. So maybe, that could account for a slight difference in performance with the charcoal delete.

Mainly, I just noticed the sound getting a little louder when I just did the charcoal delete by itself.

Highly unlikely you will "feel" the difference.

Charcoal filters are not going to make a dramatic difference. It will definitely not effect the transmission (they are not even linked together)
The main purpose why charcoal filters get deleted is to help the engine breathe a little better.

Keep in mind it takes a couple of cold hot cycles for the computer to learn the extra afr to adjust. That's with most cars with obd2 give it a couple days

jacob502

why didnt you switch to sport air filters?

DD GT3 RD

all in your head. my highest dyno without charcoals wasnt as high as with them. but varied within the same amount. id say no different

cyberorth

I am keeping mine on my second C63 as I didn't see any benefit from removing them from the first one.

DD GT3 RD

good choice. I see no reason to do it. If I got a new one I wouldn't do it again.

Making the intake path more free flowing is an easy way to up the db of the exhaust a little. Cold starts definitely bark louder.

Yuille36

The purpose of the charcoal filters was to captured emissions vapor from the intake manifold. Removing the filter will help the engine breath easier, some people have experienced CEL, error codes. I just left mine in place. I was told that you could see as much as 18 hp, but really can you feel that in the seat of your pants, I don't think so.

ZephyrAMG

Took 'em out, no difference, got CEL, put 'em back in, no difference...its all just BS and rumor...

Just keep them in. IT WONT MAKE A LICK OF DIFFERENCE.

FWIW I took mine out and replaced my stock filters w/ K&N's when after I got my tune...can't really tell if it did anything or not from a performance standpoint but the car does bark louder on cold starts.

Cifdig

There's no way you can get close to 15 hp with removing filters. If anything and if your lucky maybe 2-4 hp if that. What your looking for when doing cai and free flow exhaust is TQ. When you free up flow it's TQ you feel the most, response time etc, but with drive wire it's hard to tell. Get a sprint booster and then free up flow you will start to feel some what of a diff

gstatus929

car does feel like there is more engine noise so im sure the charcoal delete did that.

Question is how do i put them back in lol , which way up i cant figure it out.

jacob502

I'm reading posts above and really laughing. Saying Charcoal deleate wont make a diffrence is really pathetic.

By the way,you wont feel a diffrence by Removing them and driving the car immediatley. The ECU needs to adapt to the new airflow.


Do this man, and trust me, I know what I'm talking about. Remove your charcoals and panel filters and replace them with sport filters and you WILL feel a diffrence. Anybody telling you diffrent stories about a CEL and some other problems, is coming from a person who hasnt tried it. My car is a US spec and I had a charcoal deleate with sport filter equipped. Until this day I had no problems and no "Check engine light" the only thing being checked are my tail lights by my oppenents when I'm smokin em


I dont care about what you hear, get two stock C63's. One with a charcoal deleate and sport filters and the other kept the same. The one with the charcoal deleate will win. I gurantee it

ZephyrAMG

The ECU will not "adapt" to a ALMOST TOTALLY NEGLIGIBLE air allowance. I'm laughing because you are seriously delusional. The car already has a MAIN filter that does 98.5% of the work. The charcoal is to remove certian emissions and contaminants, and it does NOT cause more than 1-2% air restriction. This effect is ALMOST unfeelable and ALMOST un-testable. You are dreaming. Like saying that if you remove the wood panels on the inside and replace with Carbon Fibre you can feel a difference...

xtyper

I tend to agree with this, as I think it was already proven through the Propain vs JonsC3 runs where the only difference between the cars was the K&N filters/charcoal deletes. Propain's car with the K&N filters & charcoal deletes clearly had more top end.

JeffDL

I'm just laughing because his posts are all the same arrogant bs. "I KNOW" "I'M THE EXPERT" blah blah blah. Isn't there an SL forum?

gstatus929

I just dont want to get a cel so as my main post states:

CHARCOAL DELETE:

PROS

VS CONS

ZephyrAMG

Not necessarily and not sold on that "MOD". All engines differ slightly in build. There many factors that can make an engine more powerful on top end...there will always be differences in ability/output when things are assembled mostly by hand and 2 different drivers...

A dinky airfilter is pretty negligible...

ZephyrAMG

"I AM THE LAW!"

SonnyakaPig

I've changed my filters in different combinations about 6-7 times. Never got one CEL. I believe it is easy to mess up the install, that's why I hold a little flashlight near the back corners to make sure the filters pop down in the right place. Corners of air filters, where the rubber borders are, can tear.

Then again, people have seen CEL's from messing with filters so I guess you have to experiment with your own car.

bushburninc63

i agree with you on this statement.
