Thanks for this thread , itís perfect timing since Iím on the fence trying to decide to pull the trigger on the Turner CSL Intake GB.

The Smog issue is a major reason Iím leaning towards not getting one. Arizona is less of a hassle than Cali and NV. They do a visual as well here now.
I canít even tell you what I deal with getting my 2500HD to pass Smog.

If it failed smog after installing it then what??

Everything that they check showed ready, so all emissions related components. I live in CA, but keep my M3 registered in AZ because I still own property there. CA you would need to 'know someone.'

That being said, a lot of people have had trouble with the OBD on the CSL software interfacing with emissions checks through OBD. Mine has worked the past 2 times. I have had the CSL intake for 4 years, so I have gone through 2 emissions checks. I am currently due to do it again.

The funny part of my CSL software is when it talks to ISTA on Andrew Lang's computer, it outputs only in German. Kinda odd.

Not just Andrew Langís. Seems like bmw just never made English scripts for the CSL. Probably wouldnít be that hard to translate... except I have no idea how the ista / dis scripts are formatted.

This thread is perfect timing. I been on the fence for awhile. But the nobody mentions the additional costs just as alpha-n, parts ect. I'm happy with my eventuri intake but I want that csl roar. Want vs need

FYI, depending on how you do the OE MAP conversion (eg, properly de-pinning instead of janky splicing) you can simply remove the CSL airbox and run the OE airbox with the MAF sensor 'plugged in', leaving the MAP actually plugged in. It runs just fine for smog visual, and takes approx 10 minutes to remove/reinstall the airbox. Aftermarket MAP is a lot more obvious than OE MAP. I zip-tie the IAT under the airbox when doing this; it works well enough to get to the smog shop and be tested and to not have to rewire anything.

That does NOT fix the issues with getting CSL software to be read by the OBD scanners at smog shops, but DOES fix the visual issue.

Another perk about CSL software is it is MUCH easier to get the monitors to set. Downside, again, being it doesn't talk to smog shops consistently.

Point being: physical smog compliance is a cakewalk with the CSL airbox if you have sufficient skills to change your oil yourself. Software compliance is a total crapshoot. Smogging headers is orders of magnitude more PITA than the airbox IME.

This is a good reality check thread. I posted this in the group buy, but worth reposting here. Gives a decent cost breakdown:

One good point I think that usdmej is trying to make is that beyond getting the box physically installed with all the sensors and bits and flashing a CSL tune to your DME, your car may, for any number of reasons, not run perfectly with it, even with a custom tune. This could be due to any number of small problems one's car might have that are imperceptable in a stock airbox set up but could be exacerbated by the CSL airbox setup and/or the accompanying tune. If that happens, it might be hard to get a tuner or shop to work with you with enough patience and willingness to troubleshoot and figure out what the problem is and get your car to run right. Not everyone will run into problems like this, but I think he's trying to indicate that past threads show that people have, moreso than with, say, exhaust mods, and in those cases it can be a headache.

This isn't an unreasonable concern, but, to me, it comes with the territory of modding and I'm going to (possibly unreasonably) great lengths to make sure that my car is running perfectly and it has no small gremlins before I do any modding/tuning. Everyone's experience will vary here.

$3100 is actually not bad for a Karbonius cf csl intake w/ hardware. Good and helpful thread!

A lot of valuable information here. The CSL airbox and tune were the best mods i've ever done, but also introduced the biggest headaches for me. For emissions and readiness to show up for me, i had to get a non-csl DME and had to remove the snorkel. The snorkel really limited airflow and kept stalling the car. Now that i'm moving to CA, I need to figure out what to do.

The best mods i'd recommend for someone are cams, dinan throttle bodies, and 3.91 diff.
