Is this a Carbonio Airbox?



Saw the car on ebay:

Not sure what brand that is, but it sure doesn't look good.

obsidian05e55

Yeah, that looks horrible.

I'm prettty sure thats the Carbonio. If its old and you can't get anything done about it I would consider painting it to match the car. That would look better and keep the improved air flow. Just a suggestion.

That sure looks like a Carbonio. I have 70K Klm on mine and 25-30 track days on it (Serous heat) Mine has greened a little but nothing like that. It would take some very serious heat to make it go that yellow.

Keith had a great suggestion......

That is a Carbonio Airbox.
I called them before I purchased mine and asked about that. They said it would not turn yellow & if I had any problems to call them & they would correct the problem.
Yours is definitely yellow I would call them and complain...

For the $$ we paid it should not do that.

i have seen E55 CF air boxes turn yellow in the past.

Is there a clear coat on there? Looks like they may have used a lower quality (or at least a lower heat resistant) coating of some sort on there?

Maybe a chemical reaction with some sort of cleaner used on it?

That looks really bad. I think the heat is caused by the Renntech Stage 2 tune that the car has:

This has been covered in at least 6 threads across multiple sections of the forum. The Carbonio Carbon Fiber products tend to turn yellow after some time. I've seen them turn yellow in as fast as 6 months and as slow as 2 years. This has happened on every single Carbonio product I've seen at the track from various members in the past 3 years. It is only a matter of time until it changes color, but it will eventually turn yellow (sometimes it will turn light greenish first).

In comparison, I've seen RENNtech carbon fiber air boxes that have been on a 55k engine for 5+ years and they looked almost brand new

Someone's been looking at C63's on eBay!

Pretty sure it's not the OP's issue - I noticed that yesterday too when I saw the car in question on eBay.

Correct! I was checking out eBay and can't believe the seller will post those pictures. This proves that the car was pushed to it's limits most of the time. Like North 44 C63 said:

Actually, I have their carbon fiber engine cover, and it has yellowed a little by just sitting in the garage for one year. I never put it on the car. Sure there were some sun exposure in the garage, but most of the time, conditions were ideal. I have to say though that my engine cover is not as half as bad as those pictures.

Was thinking about getting the Carbino Airbox yesterday, glad I saw this thread.

Are there any airboxes that won't change color?

cls55

i have 2 carbonio intakes for cls55 and ml63 the 63 came greenish but the 55 was and still balck.i think the were made with different methods

Most probably cheap resin used during the prepreg process.

I had good results in restoring carbon motorcycle parts with the following method.

Sand the part with 600 grit sand paper, take your time making sure not to damage the weave.
Mix 20% black and 80% clear heat resistant paint and apply two coats. Then another coat of 100% clear.

Although it'll look a little bit darker, the fabric structure is still visible.

Damn and I thouht mine was bad....

RENNTech?

BO Knows

Yes, RENNTech never turns yellows

BO Knows

Or the 63 engine runs hotter?

MB_Forever

RENNtech's carbon fiber airboxes won't change color much (or at least I haven't seen one that have yet). As I mentioned earlier, at many of our track events, I would see some RENNtech air boxes on several E55s, some of which have been installed for 5+ years (and we all know the 55k engine generates an incredible amount of heat), yet the carbon fiber airboxes looked almost brand new (no color yellowing, no peeling, no cracking). On the same car, the person would have the carbonio carbon fiber tubes, and they looked yellowish/greenish/discolored compared to the RENNtech carbon fiber pieces (installed under the same hood on the same E55).

BenzoBoi

That's the new yellow CF option...

Someone earlier in the post said it right. I'd just paint it to disguise that horrid color.

Merc-Skycap

Call me crazy but unless the car is Rennteched out or a C74, the big black RENNtech logo on top really looks strange to me.



Wish they had it w/o that......

did someone pee on it?
