Default Streamline CSL/R airbox review - ongoing

So I stated a while back I will put my money where my mouth is and I have followed through with this promise.

I got an email directly from Antony end of May about his intentions with the airbox and asking if I would do an unbiased review of it for a slight discount on a first batch special production. Yes I know you are all going to say this is already biased as I am getting a discount - well technically no, as technically I have far too many airboxes to actually warrant owning another. But I want to give them a chance to prove themselves and given the passion Antony has shown to me in private messages I placed an order and paid in full for a first production airbox:

I thought I would review the full purchase experience and the product itself (when I receive it) so everyone can get an unbiased idea about the product and company.(this comment is in no way a dig or reference to other threads about Streamline just to be clear as I am not actually party to those transactions and there’s enough discussion about those anyways - but the elephant in the room has to be addressed)

PLEASE keep this thread clean with comments as I don’t want it cluttered with comments about past purchases, bumpers and boots which I have no direct experience with - this is about me and streamline and their airbox. For the community - an extra choice in the market.

I will be as precise and fair as I can be about it and I am sure feelings and egos will be hurt in the process - Antony knows this and he’s quite happy to take it on the chin. Am I taking a big gamble with my money? Perhaps, perhaps not? But I will not know until I see the product in person.

Anyways:

Timeline
30/5/2018 - email received from Antony
Many emails later
5/06/2018 - airbox ordered through online link and paid via CC - the whole purchase process was easy and the website very intuitive to use with shipping details and delivery addresses all easily marked on the website for a trouble free purchase experience. A++

At this point I am told
Around 20/6/2018 the first box will be test fitted to car and if there are no issues they will follow the scheduled production timeline for this first batch. Dynos ect will follow when time is available.
1/7/2018 scheduled production to begin for initial customer preorders - they have set themselves a 4 weeks production schedule for up to 10 airboxes as told via email to me.

If it all goes to their plan, they expect to begin shipping mid July for the first airboxes.
One thing I will note, it states on the checkout screen that shipping is 3-5 working days - I actually find this to be unlikely given my experiences from purchasing goods from that side of the world, but we shall see. I am putting it down as a website error and I expect shipping to take at least a good week and a half from that part of the world to me.

To be continued ....

I would consider this to be the definitive review on this product, assuming they are all at the tier of the box you receive. No one has as much insight on CSL airboxes, be it OE or aftermarket, as you.

I look forward to your thoughts.

Thank you for the comment! I will do my best and be precise with photos ect.

The comparison will be made against OE mostly as I believe this is what people prefer to know rather than against a competitor airbox.

I would like to see it compared to Karbonius myself. Especially when Karbonius claim it was molded off their box and not OE. If any unbiased person could tell it would be you.

I am just excited to see this whole aftermarket airbox segment go up a few notches recently.

I think it is fairly obvious it was molded off the Karbonius box (I might even have seen a box number if memory serves and it was 2xx - so second reiteration box) - there’s more than one give away clue to that and I don’t think Streamline have ever denied this either - they just haven’t specifically said so - more a neither deny nor confirm silence. But if you watch the videos it is quite obvious.

Always nice to see unbiased reviews, can’t wait to read yours.

Although, the main issue would be consistency. Knowing that you will be giving a review of their first box this far in advance, we know the box you get will be thoroughly checked prior to shipping. Pretty much, you’ll get the best of the batch.

^ agreed. You should get a random production model.

Both fair comments and I guess by me documenting it and having good photos up for every important detail (including fitment ect) it can be seen as a goto reference for future purchases. It can be the yard stick I think? To be fair it works both ways - a documented purchase of a product which shows what they are capable of making both here now and ideally all subsequent productions.

If anything first productions should in theory be the worst of the full production life cycle as you assume improvements will be made from my reviews and subsequent purchaser feedbacks about it - similar argument can be said about the Karbonius, with each iteration it has gotten better than the generation before it.

All assumptions of course and I am sure the skeptics out there will say otherwise - all understandable. But hopefully what I get will not only be what Streamline is capable of doing one time but all the time. Of course all of this is out of my control, but in my opinion there is every reason to keep up production quality if they want to be in this for the long term which I believe they do (extensive revamp of the front bumper shows this in my opinion). But as I say, we shall see. I am keeping a complete open mind about this and I hope my contributions and feedback about it will benefit not only the community but also the manufacturer directly.

Was going to say the same thing

One important aspect of making CF parts seems to be the molds. Karbonius invested in aluminum molds, and their recent version of the airbox is far more consistent than the previous versions.
