I actually noticed the "coupler" on the BMS DCI intake has the same outside diameter as the stock intake coupler piping lol.

[Ilma]

That's exactly what happens on my BMS DCI......the open end starts to ripple indicating it is being squished to fit.

Again...not a big deal, but this doesn't happen when put the stock airbox back on. It's perfectly sealed - not rippled.

Once again, it's not that big of a deal. Just pointing out the facts.

Sounds like a job for duct tape.

[Zeph]

I think the Vishnu is slightly larger and doesn't crush the piping... but then again, is it worth the significantly higher dollar amount?

[z06user]

I agree with what was said earlier, why not just use a little tape if the diameter is too small, rather it be smaller than too big, right?

...or just do it right from the beginning.

Aren't you the Home Depot intercooler guy? Who was blasting all the overpriced intercoolers sold here and so you kludged one up? I'd say a $95 DCI that has allegedly extremely minor fitment issues (fixable with literally $0.25 worth of tape) is a good deal.

Not criticizing your intercooler, I thought it was brilliant as I can't stand the BMW surcharge on a lot of parts sold here. Anyway I just bought a Cobb and a BMS DCI, have not installed them yet. Will need an intercooler soon...

Yes I am, but that doesn't take away my expectations on a tuning company to make things right from the beginning.
One should absolutely be able to design a well functioning DCI intake for $95, with a good margin.

I haven't stated that Vishnu's DCI is reasonable priced, only that it is well designed.

OK point taken. When I get my BMS I'll see how good/bad it is.

Had to get the plastic super hot in order to fight the Stett CAI on, and am surprised it didn't break the inlet pipes.

I had to get the piping hot when i removed the AFE DCI as well...im looking at buying the bms dci...and wanted to know if the vishnu is the same even though it cost more

[D335NUTZ]

Had a good laugh reading this thread as I took a shit.

[Butters]

Not sure the od of the pipe that bms or other co's use, but 2.25 id pipe is available at just about any auto parts store and has an od a couple mm's larger than 2.25 od pipe. It fits snug into existing inlet tubes.

Either way the rubber accordion is moving +-1mm. All the metal coupler intakes use the same size 2.25" piping in to the accordion tubes. 2.30" piping doesn't exist. Some intakes take the 2.25" and then muffler expand it to 3" on the other end to give the impression of a tighter fit. It's still the same size pipe going in there.

Don't buy the BMS DCI, its clearly deffective.



I really cannot believe this thread.

Well I installed mine just now. I think it is a stretch to call this an intake kit, what it is is 2 K&N filters and two pieces of cheap pipe. However, for $95 it is fine. The issue with fitment was not a big deal. The pipe is slightly smaller diameter to get it deeper into the accordion part of the tube, which is narrower than the outer lip where the OEM airbox clamp tightens. I can see that fitting the new pipe into the very end of the OEM plastic pipe might not be as secure as the filters move around. The OEM airbox is hard mounted.

Anyway if someone were to make cast or machined pieces with stepped diameters to a) clamp at the larger ID of the OEM tube, and b) slide deeper into the accordion part, this would be a $250 intake kit.

Sound is fine at least I can hear the turbos spool up now, + a bit crisper throttle response. Cobb goes in tonight...if UPS doesn't get here too late.

The Vishnu DCI attachment tubes do it that way.......the small end is 2.25 inch OD to slide easily into the accordion hose.

The end that slides into the filter is flared out to 3 inches.

About $100 cheaper than your price point, but still more expensive than BMS.

OK good to know. Since the air flow is limited by the 2.25 part, I am not sure you get much more air. But you don't have to crush the OEM plastic. A ram on the filter end is good, too. Smooths out the air flow. From past development experience on older BMW's there's a limit to what an intake can do, and one you remove the biggest restrictions, very little HP left on the table.

I think at 200 I'd be pissed at the BMS DCI quality, but at 95 it is fine. Seems to get most of the big restrictions out of the way, and some cold air still gets in there from the factory duct.

I just installed a BMS DCI on my 335i today, I like it alot. I bought it used for $50, so I really really like it alot! I also have a 92 325i with an afe intake that cost more than a Vishnu and a BMS put together, and it fit terribly! If you have any experience with aftermarket parts, you know "perfect fit" should never be taken literally. Thats why BMW charges an arm and a leg for a small "$2" plastic part. After 12 years as a Master technician, and modifying many cars, I have come to expect imperfections. And "you get what you pay for" is not always true.

[MikeyComputers]

I just did my mr.5 intake and getting my stock airbox back on those tubes was a pain in the ass.... i had to take off the front hvac filter and plastic underneath to muscle that thing back on it deff shrinks .... oh btw my ait dropped from 135 to 108 degress instant after Mr.5

I wish Eurosport High Performance would make an intake for the N54. For track use, I'd definitely leave the stock box back in without meth injection.

BTW we dynoed a 7 HP loss with an AFE intake on an S52 versus a stock Euro 3.5" airbox.

Are you saying your IAT dropped after putting the stock airbox back in? I guess that makes sense, but the airflow increase, albeit hotter air, still makes more power when you're running a lot of extra boost over stock.

I have an '08 335i coupe and installed my new BMS DCI lastnight. Install was somewhat easy, it took me 50 minutes exactly (yes i am somewhat of a novice) do to issues of mounting the intake that is closest to the driver side. The tubing to my knowledge fits just fine, I did have a few issues actaully getting the pipes in the intake tubes of the car and that was do to minimal space to work in and minimal light (my girlfriend can't hold a flash light for shit!!!). Eventually, I got the BMS intake tube in and it fit fine, I will be checking it again tonight (only because I am paranoid and like to check my work repeatedly). Installing the BMS intake tube to the section closest to the front bumber was the easier and fits greats.

With the hood up, when reving i hear a loud SWOOOOOOSH sound and it sounds great when driving it too. I notice better throttle response, a throatier sound from my exhaust, and notice MINOR power gains (i have not done a WOT run yet).

Overall, I feel this is a great product but do wish the instructions were slightly better interms of informing one of the road blocks they may encounter during the install.
