hi
did anyone ever try this intake?
how is the sound difference?
was it worth ?

You'll get differing opinions but any "filter on a stick" like that is prone to heat soak.

There was one recently offered in the dealer classifieds that had a heat shield.

I just bought a b58 BMS filter on a stick and I'll see how it is.

I used to have he n54 dual cone intakes by BMS and they were rock solid with no issues. Hopefully the b58 version is just as nice.

AFE is having a sale with free shipping, I just got an email about it. They make a true CAI as does Dinan. Those are the two I'd check out, think Eventuri makes one too but that's real big boy money. Both AFE and Dinan are around $600, between the two I'd take the Dinan one.

ok thanks i will check it out...but its expensive for an intake !
so no one really tried this one to give a honest review?

[B58togo]

I have this one on my 240. It's not as noticeable in the cabin as I thought it would be, but once I added the JB4, the sound became a bit more pronounced. It has a nice whistle. The quality/fit of the billet is outstanding.

Noticeable sound increase, its a very popular choice

[Shayan55]

I have the BMS intake and love the sound and i noticed a slight improvement in turbo lag and throttle response, but that may just be a placebo effect. But all in all im happy with it.

I tried it. The sound is great if you like blow off valve type noises and it looks nice under the hood. Personally I got tired of the "whoosh". I also had issues with hesitation on acceleration, BMS told me it was likely due to the MAF and suggested I run the car without the MAF plugged in. I wasn't a fan of that solution so I ended up taking it out and bought a k&n drop in, that's what I'm running now (I'm FBO btw). I'm sure I could've done more troubleshooting and figured it out but it just wasn't worth it to me.

I have it on my M235i, the sound improvement is great. You will hear the turbo spool up up and blowing off. And you would want it when tuning the car with jb4 or bm3 as it will require more air to suck in .

In my opinion the heatsoak stories are just bullsh*t, just get a proper intercooler.

I would amend your comment on heat soak being "bullshit." Something like the Dinan CAI or Eventuri (big $$$) do pull in cooler air. So the actual engineering or science or whatever you want to call it isn't bullshit. That said the actual importance may be bullshit. As great as the engine in the car is, for what it is, it's not an F1 engine where microscopic things have a huge impact. So yes at an all day track event you might see a bit of benefit. Regular driving probably won't notice any difference from a performance perspective.

Testing was done on an N54 but same applies to this engine as well

Repost from 2012:

So for this round of testing we used our 135i which happens to be 100% stock at the moment aside from the JB4 using 91 octane + NOS octane booster (~93 octane). I've been testing map 2 with a default CPS offset lately so kept that all the same between both tests.

The two sets of tests were performed within 20 minutes of each other under identical conditions. First I did a 40-110mph sprint (on a private track) to evaluate the intake temperature increases throughout the run. Secondly an 8 minute (limit of JB4 logs) idle test simply logging the car with the hood down and AC on to monitor intake temperatures at rest.

According to "hot air" conspiracy theorists the dual cone intake should result in higher intake temperatures during the wide open throttle run, no power gains, and heat up dramatically sitting at idle soaking up all that engine heat.

First up: Stock intake system



Next up: BMS Dual Cone Intake


Results:

I hate to say it again but the results were exactly as expected. The DCI did not produce higher air intake temperatures at wide open throttle, did not heat soak more sitting at a standstill for 8 minutes, and all around felt faster. I should also add it's certainly possible modifying your OEM airbox with an extra filter might offer minimal gains over a dual cone intake assuming you don't mind up cutting up your factory airbox but don't expect much. We've tested this as well with no significant performance gain over a DCI in 40-120mph VBOX times. You have a lot of options for intakes but three+ years later the tried and true DCI is still the intake of choice for those of us who are serious about performance...

i would have to agree also, i have the bms intake with a AA intercooler and for street/light track use its fine.

[Benandluna]

No problems with the Dinan CAI, nice sound, felt a small throttle response increase. nothing major. Cant tell you if there is power improvement from the butt dyno.

[Jeff@TopGearSolutions]

Dinan is one of the better intakes, I prefer the closed box style intakes from a performance standpoint.

However, none of these intakes add gobs of power.

Choose one based on power, sound and or looks.

Also, intake air temps are largely weighted by the FMIC. However, cooler air to the turbo's would yield more efficient power.

What was the ambient temp during this test?

Which temp sensor was the data obtained?

Post was 5 years ago, unfortunately i do not remember all the details. Im sure Terry would know though.

Test was done same day so ambient is the same for both intakes and starting temp was at 86 for both

Good questions to ask though for sure. Mike - not directed at you in the slightest. It's always good to know all the input parameters. Coming from someone who has charts put on my desk all day long, you can always make things look exactly as you want them to if you "twist the knobs" on the inputs, so to speak.

Agree!

There have been a ton of discussion about these tests, google the original thread and im sure all the answers to your questions will be found there.

If you still have questions, i will be more than happy to ask Terry. Highly doubt he will remember specifics but no harm in trying

[Benandluna]

Just get the Dinan one. It's one of there better products and the sound is awesome

[dukeapenguin]

I’ve used AFE one and BMS one.

1. Intake wont add hp
2. BMS is f***ing cheap
3. They all have good filter
4. BMS sounds much more better
5. No there was no IAT issue
6. You def get idle issue on BMS intake, but I never idle my car, its just very small vibration during idle.
7. SO I got BMS, better sound, cheaper price, just don't look good.
