Would anybody be able to comment on if there were any discernible differences in the sound quality/volume between the CF and OE trumpets?

Shipping and payment updates


Payment
There are no partial payments; we will go down the list and invoice each buyer for the full amount when your box is ready.

More info coming next week (week of March 12th) on how we'll take payments


Shipping
Will be shipped with DHL plane. It takes 4-5 days to arrive depending on customs.

Production rate for our group buy
Airboxes can be produced at a rate of 2-4 airboxes per week. Specifically, the rates are:
3-4 per week airboxes with OE trumpets
2-3 per week airboxes with carbon trumpets

Pending confirmation: We estimate we can start shipping the first airboxes out in ~2 weeks (starting week of March 26) if we start production week of March 19.


Costs
To USA is 189 € or ~$232.55 each box.
Please ask for any additional rates

I will ask Karbonius if they can work with us on combined shipping. I asked previously but will see if they can work with us.


Differences between the airboxes
The construction of this box is the same. The main difference is the trumpets, warranty and how it is cured. All molds for the CSL airbox and the CF trumpets are made of aluminum. This allows Karbonius to make parts in autoclave at higher temperatures and pressure. The quality of parts produced with aluminum molds are of higher precision and quality over fiberglass molds.

CF trumpet airbox
✓ Carbon trumpets OE length
✓ Cured in autoclave at 135 C and 5 pressure BAR
✓ 1 extra varnish layer
✓ 5 year warranty

OE plastic trumpet airbox
✓ OE plastic trumpets
✓ Cured in autoclave at 120 C and 3 pressure BAR
✓ 2 year warranty

I will "close" the group buy once we have 20 people signed up. "Closing" will mean I will ask for confirmation and collect order info from each buyer to send over to Karbonius to start production.

#21 and onward will be waitlisted so continue to sign up as people will drop off like in most group buys. Once you drop off, you will have to go at the end of the line if you wish to rejoin.

Awesome news and looks like things will be progressing quickly, just what I wanted to see. Track season coming soon so definitely want this baby in the engine bay before then.

Thought I saw their recent post mentioning that their CF trumpets are 8mm longer than OE. Can you please confirm this?

Edit: I found the post you are referring to here: https://www.instagram.com/p/Bf-PR7wl...n-by=karbonius

As you can tell, english is not their first language. I will ask for clarification on what has changed. It might be the mold being 8mm longer and not the trumpet itself.

^ thanks for taking the initiative (or seeing the opportunity!) of putting the GB together.

I'm curious about preferred tune, and oem parts required to successfully install this box. I know that others (Leighton, for example) have listed this stuff elsewhere, but is there and preference/spec from Karbonius on the matter? Their website/social media is vague on this topic. Wonder if they could provide commentary given the current csl box blowup around here

Just trying to help the community out. I prefer Karbonius's airbox over all available due to their design principles and long history of producing quality products.

There's some info around the forum, but as always with forums, very difficult to find. I will do my best to put it together once I have time. My main priority is getting this group buy going first.

Someone suggested packaging up everything else required for installation. Great idea but that's not something Karbonius will do; it will have to be me. So if anyone has connections for the other required parts, please send me a PM.

Personally, I will not be doing the alpha N route and going with the HP DME upgrade with CSL tune.

Will we be able to get the ITG filters ordered when we order these? I’d like to order 2 ITG Fikters when I order my box with this GB.
