People, people. There are now different flow characteristics. The MAF will adjust....don't get your panties in a wad.

Does not fit. Hits the oil lines. Also the tab does not fit correctly in the recess.

Exactly. CEL = IM OUT

Pros:
- Sound is great, and not overly loud with the excessive surge/induction roar like Eventuri intakes have. Imo it is the right amount of turbo spool and drama.
- Call me crazy but the car undoubtedly pulls harder. I have installed a CAI on atleast half a dozen vehicles in my lifetime and never felt a performance gain before. With this intake the car feels like it runs stronger under WOT. (I am currently stock although I have a pile of FBO parts and a PS2 turbo going in any day now)

Cons:
- Aluminum is THIN, as so, I decided to install thermal gold tape.
- Fitment leaves something to be desired, although it looks pretty good installed. The port for the MAF is very tight and it is not seating as flush as id like. I will make some adjustments to try to correct this. My biggest gripe is the flared end of the intake that mates to the OEM plastic plumbing is smaller than OE. Because of this, it requires you to tighten the worm clamp down excessively. It holds securely but I'm not a fan of the fitment here.
- Last and most important, throws a CEL. Have not coded it yet but the car runs fine with the light on. I will update this if it goes away, although I doubt it will based on past experience.
- Idle is rough upon start up, and throttle response is abrupt in sport mode at 2k rpm when driving civil in a higher gear.

I am happy to confirm this CAI will fit over the metal lines as an above user had concerns over, and I did not have to modify anything to get this to fit. It was very easy to install and literally took 5 minutes.

I will sell this for a steal if another member wants to try it, as I don't plan on running JB4 to code this CEL out. Shoot me a dm if interested (San Diego, CA)

Interesting. The one I received the MAF and DCT port are flip-flopped. Further more the CAI hits the oil lines even before I attempted to tighten down the bolt.

Curious if this will increase the odds of a CEL

I always recommend a JB4 with open intakes so you do not have to worry about the CEL

code clearing is no longer available in the USA for CARB certification. The only way to really get rid of the CEL is to get a flash tune for speed density tuning.

I don't think the MAF will adapt as it is used just for idle conditions and is really sensitive to air flow changes so the ECU can't really compensate for it. The F series N55 has a whole thread on 2 addicts (m235i section) of users complaining about rough idles and even after months the car never adapted.

Fuelling trims and ignition tables can adjust over time as they're designed to adapt and learn, I don't believe the MAF tables will do the same to such an extent as it is used sheerly for idle and likely emissions. Because as soon as you're on load the car switches to speed density.

can you slide it around on the intake clamp side? I know the boot end that the intake slots into can wiggle around enough so the clip can get closer to it's proper location and better clear the oil lines. Then there should be enough slack to pull the end of the intake further out of the boot to help clear the oil lines if need be.

Otherwise i'm pretty interested in this as I wanted the BMS intake for my m2 as well.

Your thinking of CEL caused by downpipe, im talking about the MAF sensor.
The Jb4 will override the MAF sensor

No I'm talking about the maf sensor as well. No it won't the jb4 doesn't override the maf, when you run jb4 "mafless" you unplug the maf sensor from the intake forcing the car to go into speed density mode by itself, thereby overriding it. This causes a check engine light which the jb4 used to clear, before auto clear was disabled.

This pretty much eliminated the use of the maf at idle conditions solving the rough idle and cold start rev hunting a cold air intake causes. It was a pretty smart and simple solution that doesn't require a flash and uses the ecus own back up system for the maf. But now that code clearing is gone it will be a bit annoying to use. But I heard you can sign a wavier to acknowledge carb certification will be void in order to get those race track features (code clearing) back.

Also code clearing for the downpipe or the maf is the auto code clearing feature on the jb4, that was removed for carb certification.

If you unplug the the MAF sensor and turn on passive delete, the Jb4 will suppress the code.

And passive delete is disabled in order to get carb certification, there was a whole thread about this on the other forum. In order to get passive code delete back you must be outside of the USA, or sign the wavier acknowledging the jb4 is for off road usage and with that new firmware it is not carb certified.

Ok so JB4 will suppress the code as long as you sign the waiver

Yeah you sign the wavier and they'll send you the specific "off road" only firmware. Or if you're outside of the USA the jb4 updating software will detect that and automatically allow you to have auto code clearing.


I believe this is the only feature they removed as well.

Did bms reply? Could you also post pictures of the fitment issue?

[MZWIE]

I spoke to BMS. They mentioned that the aluminum version is not meant for the M2.

Only the standard CAI will fit. However, looking at the pics of that one I don't see any advantage over the OEM.

Sending this one back EPH for a refund.

Oh dang that sucks, I really wanted the bms one because it's more affordable than injen.

The benefit is that the piping diameter is larger than stock with no bottle necks which the stock one does have right in the middle where it tapers down quite a bit. The only con is I've heard the plastic bms one warps if you tighten the clamp for the filter too much.

BMS doesn't sell performance products in California anymore, I don't believe they care about the CARB certificate. The auto-delete might be back on in the latest firmware revision.

I guess the heat from the flash tune competition made say 'F U California & Mother Nature, we gotta eat too..'
