did you get this new and if so, how long did you wait for it? did you buy it from their online site?

Yes I got it new, it took 10 weeks to get to me after I ordered it from a Canadian reseller that deals with IND Distribution. IND Distribution is the North American distributor for Karbonius.

Ordered March 6th 2025 was shipped to me May 15th 2025.

Looks absolutely great man! I'm itching to get mine on, had it in the closet for a year. It's a Karbonius 2x2 weave though to stay true to the CSL but everything else is 1x1 on the car so I love that tight knit weave.

Thanks!

Your restraint is unreal—I wouldn’t last a day before this thing started yelling from the closet to get bolted on! 😆

I chose the 1x1 weave since my vert’s never gonna pull off the CSL look, so I embraced the unique vibe. Sometimes a tiny voice whispers, “Should’ve gone matte,” but it’s drowned out by the glorious roar of my intake!

Someone say matte 1x1!?

Gat dayamn. Can someone tell me how to one installs those f'in throttle body clamps btw? I'm just going to go with screw in clamps (and make sure they are out of the way)

I removed the air rail then used this tool to secure them. It really wasn’t too bad once the air rail was off. The right tool makes it pretty easy.

Yep, I did the same thing only difference is I got fleeced on the cost of the CV boot tool cause Snap-On... I used the (11617830306) along with these for the OEM clamps to the airbox side.

I wish I could run that side but I have the flap motor in the way, I suppose I could hack it up and try but it looks like quite a bit would need to be cut away.

I don't like the way these shields look but I would think they would help direct more air from the fan down the sides of the motor. Is that the main purpose of these?

Yeah, that's the main focus. These shrouds are SO effective at that.

Correct me if I'm wrong but the CSL omits the driver side shroud. I'm not planning on running mine.

The CSL indeed omits this part, but if you are not running the flap there is room for it, and I would personally run it for potentially better cooling.

I must say I like the look of the enigne bay sans these parts but they are there for a reason.

I don't particularly care for the asymmetrical look of just one shroud that is why I attempt to hack up the driver's side piece to fit around the flap motor.

Man these karbonius airboxes are straight up gorgeous.

Let's say one was (theoretically) living in an emissions testing state (car gets hooked up to the computer). Given state has an emissions exemption after model year reaches 25 years old as far as I know. Would one theoretically be home-free on all the remove/re-install chicanery around inspection?

[discoelk]

My car passes obd 2 emissions check fine with the CSL software in the metro Atlanta area. I have headers, quality cats, and a stock(quiet) exhaust but no SAP or secondary o2s.

Someone say matte 1x1!?

Wow, i'm sold on the matte! Is this also made by Karbonius?
