Best CSL Airbox Setup?

[Projecte46m3]

Have there been any issues with the haimus boxes since the initial switch over in company name, etc? Pricing between haimus with shipping and karbonius is nearly the same now. Small thing but I like that the haimus box doesn't have that additional roughly 2" diameter inlet on it.

Also ECS tuning is listing them as shipped from the manufacturer. Anyone know if that means it's warehoused overseas and I'm going to get a tarriff surprise?

I've been running the latest version of the Haimus airbox and it's been great! No issues at all and don't forget it has a very nice IAT location compared to other airboxes.

Did the kit include instructions for wiring and install>?

Haimus is my favorite also, never had any issues at all - not sure where all the hate comes from. The IAT relocation is a very nice touch as well

In 2025, it was discovered that "If you move the IAT from the stock location you are giving the DME a false representation compared to what it is expecting."

There is a reason it is behind the filter and not in front of it. A reminder of where they put it on the early airboxes -

I keep meaning to put mine back in the stock location.
Mine is at the end of the OEM Snorkel, I drilled a hole in it, which I am now regretting considering the cost of these. Oh well, I don't plan on selling it.

Sorry if everyone knows this for certain, but I read this and many other threads and am not clear.

Is it a certainty that a CSL airbox/tune (MAF and/or MAP) won’t pass plug in emissions? No visual.

pulling the box every year would be a deal breaker.

I just completed my install and have not yet attempted to pass Georgia emissions, but a few forum members here in the Atlanta area report no problems passing.

Im in GA and there is no problem at all passing emissions with the airbox. I was also able to pass emissions catless. LOL

I passed with my airbox in Gwinnett with a full MAP conversion. It only fails visual, and GA doesn't do a visual inspection, they just plug in the OBD2 and zug zug

This is certainly new info, and really good to know.
