Default Re: Comprehensive CSL Intake Thread

frantically searching and trying to catch up on everything to determine if i should take evolve up on their BF deal or not.

i have a 2003.5, with only CPI RTX/SS res sect2/SS sport sect 3 as mods. i think i can just flash the alpha n without needing additional tuning? on the evolve alpha-n does further tuning need to be done through evolve or can i take it to my favorite local guy to refine as needed or as things like headers are added?

the "complete" kit from Evolve at $2750 for BF would be how much if I started with the Karbonius box? there are a few little things I like better about the Karbonius box, but not sure they're enough different to really prefer one over the other?

whichever solution I go with I really need it to be as *easy* as possible. I'm in a small town 50miles away from any sort of BMW service indy and no local community, so I'm almost 100% flying solo on all of this.

Simon, I haven't forgotten about you. We will be in touch soon.

Question though. In the images below, how were you able to get intake flap to secure to the carbon fiber portion? There are those (4) screws that connect them together somehow, but not sure how you did that. In the CSL photo, there's that 1" or so "band" that is connecting the two. Just trying to understand how these two components came together.

Thanks!

CSL with a shorter suction intake, without the little extension it seems like it might be better at aiming air into the CSL snorkel opening. You could probably cut that little extension piece off the non-CSL version, just wouldn't be as clean as buying a new piece.

I used the below part #s, just little screws and self-locking nuts to hold them in place. Although the Karbonius box doesn't have the 1" OEM plastic band, it actually has a CF flange with screw holes in it that mates to the snorkel.

I actually only have the top 2 screws/nuts on at the moment, to get the bottom ones I think I'm going to have to remove half the airbox and attach the snorkel first.

That's what I'm curious about....why doesn't the OEM housing not have any sort of flange to connect the intake flap? Doesn't that seem weird? I have no idea how the two connect.

Based on the Real OEM diagram, the OEM CSL airbox is supposed to come with that plastic ring attached, seems yours is missing. Unfortunately I can't find a separate part # for it. Might be worth sending NZ_M3 a PM as he's super knowledgeable about these boxes.

You can see the piece here, but comes with 1/2 the airbox attached to it as well:

That is the P54 unfiltered section which does not have a flange like the unfiltered CSL part. It utilizes custom intake ducting. You could get the CSL unfiltered section if you want the flange since the main filtered section of the CSL intake is the same for S54 and P54, but it is a fairly pricey piece. Here are three versions of the intakes and unfiltered sections courtesy of NZ_M3.
