yup. made by Carbonio, sold around here by various vendors. I have the CF boxes in my car and like them.

Have anyone experience any hp/tq gains with these airbox?

Be careful with those foam filters.. go check your air boxes for oil.

Fr33kn63

Yeah I had to clean mine totally. Dried it out and put the K&N rechardge spray on it lightly so not oversaturated like the day i got it. Fortunatly the oil tends to drip down if you have noticed where it seems to collect sometimes.

I cant remmeber what numbers they quote, but on the Dyno you really dont see much since it needs significant airflow to be noticeable. It does seem to have soem additional grunt in the mid to upper range.

I installed the foam filters that came with the boxes I just installed the K&N filters. The boxes were soked in oil very sticky too. Thos foam one just went into the trash can. Before I put them in I completely dried them out of oil and still soked , not to mention they are all seperated and falling apart . GUYS the foam filters are JUNK, TAKE THEM OUT

Great timing on this thread, I currently run the cf airbox on my Black Series. Evosport is currently doing some extensive testing with my stock airbox, the CF airbox and a new design they have obtained. Keep your eyes peeled for some results to be posted by either me or Evosport within the next week. We will have dyno numbers to back up our findings.

We'll be waiting... Jim did you get the PM?

I know this might be a silly question but when did K&N release an e63 filter? I recall about a year ago trying to get one from them and they kept pushing me off. Started looking into the green filters, but just kinda took care of the foam ones that came with my CF boxes.
I just went on K&N's site and sure enough now they are selling them. Just ordered two of them. Anyone have experience with the K&N filter in the 63? Curious to thoughts if any...

rarfinancial

They must have just came out. I too spoke to them about a year ago to have them make some run, but they said the will not make them, lol They are a perfect fit and are not oily at all.. I just installed them about two hours ago.. I feel alot better knowing the foams are out..

So the foam filters that come with the CF boxes are junk because of the oil saturation? I thought K&Ns were bad for oil as well, mainly hearing that K&Ns can cause MAFs to go bad. I'm not sure though if it was the type of oil used with K&Ns that caused MAFs to go bad, or simply the amount used on the filters. I've used K&Ns on 2 cars however without problems.

Just curious if I should quickly dump the foam filters I JUST installed the other day. I did notice they were oily.

Fr33kn63

Yeah. Glad to see they finally made them! They told me that too. not gonna make them....lol...guess they changed their minds!
Mine should be here tuesday or wednesday.

Yeah the foam filters are kinda crap...lots of oil saturation for sure! Before I ended up cleaning mine and drying them out and reoiling properly, they dripped oil for months. Cleaned the bottom of my airboxes several times to cleam the oil puddle up.
K&N's got oil all over the MAF's in my old P-car. Hopefully these will be ok.
I had K&N's in my old C55 and loved them. Hope to love these as much. Or atleast more then the foam ones.
I cant imagine any filters showing up with more oil in them then these foam ones.

rarfinancial

The oil in the foam is very thick and stickey too . Yes, those foam filters also seperate and fall apart.. I hate to say this but I opin these fomies are JUNK.. They K&N's feel dry and they are great quality

You got me interested..... are you talking about modifications to the stock box/CF box or a completely new designed air boxes? What kind of dyno numbers can be expected on a stock car?

Common Jim....... at least give us a few hints
