I am planning on changing the two air filters of my C63 and I was wondering if there is a DIY guide available somewhere?

giovannikoll1

Thank you very much for the great video

Is that what they call charcoal delete? Or are we suppose to replace the one removed with a K&N.

I have ordered a pair of BMC air filters according to BMC the C63 has an original air filter that limits the flow of air in order to limit the power of the engine so that it is not as performant as other 63 models. By fitting BMC filters they claim an increase in hp to 500hp

noodleman

yup. When they slid out that grey filter from the black plastic bracket from the intake cover.

cptdaz

Yes, and air filters are separate filters that sit below the charcoal filters. They are there for the stricter emission standards for California.

I wouldn't buy into that claim; not even their race filter is capable of that much boost. Hell, you can run no filter and you couldn't get up to 500.

No offense to those who run BMC filters but they are overpriced IMO. I don't see why they are sometimes twice as much as K&N when the quality as far as I can tell is the same. And difference between brands of filters is minimum when it comes to performance especially with a 3500+ lbs vehicle.

I might do this...hopefully no CEL!

I guess there statement is overexagerated, howver the BMC filters were cheaper then the K&N well thats at least the case here in Europe

K&N far exceeds other competitor filters. Just look at long term data and user reviews. They are far better made in my opinion than BMC ( I have had both). Also, they have a proven track record...

Cold start is a beast when you remove charcoal and replace with K&N, however all the crazy HP increase I am really not sure of. It is obvious that air flow is better and not as restricted (this a given) but if the end user can feel themselves being thrown back in their seat....I dunno about that...

Changing these specs adds to the 'Race Car" component of the car too...

izzyAMG

has anyone gotten a cel light after this change?

cptdaz

I have the charcoal removed and filters replaced with aFe dry filters few hundred miles ago, and still no CEL (knock on wood). Did every thing I could to ensure that the airboxes are seated and sealed properly when I did the swap.

ZephyrAMG

None so far...took time to look all around box and make sure to seat right...

I just wanted to throw in my 2 cents on charcoal deletes. Having NOT removed the charcoal filters on my 09 C63, then getting my new C63C and driving it stock for 900 miles, then removing the filters today, the most noticeable change is the SOUND. It's amazing that the sound can improve so much with such a simple mod. To those who have changed air filters as well, is there whole other level of improvement to be had? Or is the major change noticed with just the charcoal deletes? I am very happy with this small mod.

Just this week I removed mine and switched to K&N. No CEL and it seems to have better throttle response.

Great video, took longer to watch than change the filters!

Does anyone know if there is a part number to replace the charcoal filter or are these supposed to be in the car for its entire life? I'm thinking of buying the filters separately to save some money at service, but can't seem to find a part number for the charcoal part...

D.T.SFK

I've heard that the OEM charcoal filters for our car cannot be bought separately, in fact I heard you can only buy it if you buy new airboxes with them. That must be why you can't find the part #s. I could be wrong, but I'm 99% sure.

tuffcalc

Interesting - then I would assume they are supposed to be good for the life of the vehicle?

D.T.SFK

That's what I've been assuming. But always better to see if any others chime in.

Dark_Knight

I'ma littel confused, so the video is of the so called charcoal airbox filter that dont do much of anything, so they can be removed with no problems, so there is another "real" air filter elsewhere?

Mort

The charcoal filter and the air filter are back to back in the air box.

ZephyrAMG

"Good for the life of the car" is just about having the filter there, present. The filter needs to remove debris from engine. Now when we talk about air restriction, that's another story. Are you "helping" the car run better with more air flow? Are you decreasing engine life by sucking more power out of it over the long term? The engine, due to it being N/A will perform better with better air flow, we all know that. But as long as you have some sort of filtration, that's all that matters.
