I'd get the AFE Dry's.. thats what most people recommend.

Doing my install today!

I don't know the differences between them lol, but i ll get whichever one gives more sound&performance gains

Any experienced users like to share the difference with K&N vs AFE ?

c63addix

Hey why did you buy the Pro Dry S instead of Pro 5 R? Sounds like Pro Dry S is easy to maintain and Pro 5 R is for maximum gains? they're both same price so probably don't have differences?

i have afe pro dry and charcoal delete and have not had a cell yet. for me any sound or performance difference was not noticeable.

c63addix

thanks for the info, and AFE website don't ship to Canada.. fail!!! Anyone know other websites that can ship to Vancouver?

deuce zer0

I was going to order BMC filters if I didn't get the AFE. I think they will ship to Canada

xcharlesy

I can get you one, I have a hook up, pm me.

Installed AFE Dry filters on my 10 C63 today, 0 issues / no CEL. But I can't see why guys get it if they aren't sealing them properly, it's a real trick to making sure the back corner goes in flush.

I think I am going to order some filters soon. Anyone have any preference between the AFE Dry and the Weistec Dry Filters?

xcharlesy

I'd go AFE, cheaper for one (depending on where you get them) and its does roughly the exact same function.

Notice any difference or is it in the mind

xcharlesy

Maybe a little sound? but I can't tell, throttle response feels a tad better, reminds me of resetting the adaptable trans on BMW, just renews how zippy the throttle can be.

c63addix

hey thanks for the offer man! really appreciate it, but I ordered the K&N filters from knfilters.ca earlier today.

I didn't want to go through the hassle from the states so i just ordered from their Canadian web store.


But can someone tell me how often I should clean the K&N filters? I m guessing every 3000 km?

c63addix

Hey guys, my K&N filters arrived but just have a few questions regarding high-flow air filters. Been reading about it online and almost every site mentions the cons are dust particles can get in easier.

But our filters will be all sealed up and also covered by the MB plastic , so I guess this won't be much of an issue for our C63's?

Also, I'm going to add oil to the filters and leave them overnight to drip all the extras. I believe this is the best way? It's pretty cold here at the moment should I leave them dripping in a warmer area lol

xcharlesy

I would stay away from oiled filters in general, lots of guys on here have had problems with it clogging the MAF, and most prefer the Dry.

c63addix

Maybe they add too much oil to their filters? I'll probably buy dry later on anyway. Going to need 2 sets lol. A back up while one is being cleaned for the day would be nice

+1 for low maintenance, no fuss dry filters!

K&N are pre-oiled from the factory, just make sure you dab a paper towel on them to take up excess oil which can mess up the MAF sensor.

Is it safe to purchase the 2011 aFe Dry Filter for my 2012 C63? Obviously no engine changes, but just wondering if I should be worried about anything.

xcharlesy

I don't know if any changes were made to the filtration system between 2011-2012, but these have been flawless in my car.

kenster96

Thanks, just went ahead and ordered them. I'll reply back within a week if I get CEL once installed.

I have AFE dry filters with charcoal delete on my 63... Never once have I gotten CEL

c63addix

lol my CEL keep going on and off I think i stop caring about it now. Everytime i do a WOT it comes on and goes off 3-4 days later..

Jon2007E63P30

Well, the computer has no way to determine the space in your air box. The CEL is most likely idle fuel mixture adaptation issues. However, it should not be so drastic as to throw a CEL, or every time you changed out old filters it would come on. It does not. Most likely it is getting the air box properly seated in the connection after the MAF. An air leak after the MAF will certainly throw a CEL.

I guess it could in some cases have problems correcting, but I guess that could be one reason for the wide variety of results.

Removed them today

Higgs Boson

I had some KNs and I tried installing them three times. Each time I would put them in, about 4 starts later I would get a CEL, it would shift wrong and buck as I rolled into the throttle. Each time that happened I would reinstall the stock filters and the symptoms would go away and then the CEL would turn off as well. The trans shifts off of torque request logic which is ultimately derived off the MAF signal, so if it doesn't like the airflow vs maf hz then you are screwed.

I threw the KNs away.

It seems like some of these cars have a wider tolerance for fuel trims than others. Not sure if it is a variation in operating systems in the ECUs or what, but there are some that can run filters with no issue. Just the luck of the draw I guess.
