Hello all. This is my first post with this forum, so I hope it proves helpful. I just bought a 2008 335i sedan, and I am looking to put some sort of intake on it. As of right now, I have been looking between the BMS and Ultimate Racing intakes. Take a look at the two links below:

http://www.burgertuning.com/products.html

http://www.ultimate-racing.com/Produ...5i_S_CAI.shtml

The way it looks, the UR one appears to be able to get colder air, since the filtered intake is towards the bottom. The engine on my car seems to run really hot, like 2 hours after the car is off, i can still burn myself. So, the UR one will be better in that aspect, since the BMS only really gets the hot air from the engine bay. However, the argument is, that the air gets heated to
extreme temperatures anyways after it passes through the turbos, that
the colder the air is at intake doesnt really matter, since it has to
go through the intercooler anyways. With that assessment, the BMS one
would be better, since it appears to be able to get more air in
general than the UR. I like the look of the black UR better, but for
$400 more is it worth it?

Thought/opinions/suggestions/other preferred intakes?

Thanks all, and I hope to be able to contribute to many more discussions on this forum.

Cheers,
M

UR...mine is in the mail. The stock intake is pretty much optimized for the mass flow of air that the engine injests so you wont find an intake out there that will net any kind of substantial gain from being 'less restrictive'. Your right about the temp increase that the air sees as soon as it hits the rotor but a decrease in temperature prior to the compressor is still beneficial, hence why the only intakes that are showing any kind of gain are cold air intakes.

UR looks better, sounds better, and performs better

Have you taken a look at the Logic HVI? It is priced right in between the two and works just as good if not better then both. Alot of my friends are running it. Check it out at www.Logicmotorsports.com. I have had it on my car for a few months and it definately does something. Throttle response is up, engine temps. are down, and power is very smooth al the way to redline. Plus, they have great customer service. Check out there website or give them a call at (714) 738-3737.

Welcome to E90post!

+1 for the Logiv HVI

It's easy to install, don't have to cut any braces or take of the fender liner.

It's made of aluminum and after a spirited drive, I can touch the tubing and it's just warm, not burning hot. The power can be felt in the higher RPMs where these turbos are gasping for air.

Logic HVI is ~$150 cheaper, save the money and spend it on other mods.

My two cents.

[Makushr1]

Yeah, I saw the logic one before. The way it is set up, makes it look like its getting pretty much the air (hot) as the BMS, and BMS is alot cheaper. Which, that goes back to my original concern, and that was is it important to get cooler air, or does it not matter bc of the turbos.

[e90AW335i]

BMS intake FTW

[Duke]

I like the Logic

[Amir87]

For turbo car, HVI or CAI doesn't matter. Regardless the air going into the intake is going to get cooled by the intercooler then it's going into HOT turbos.

On a N/A car, sure, CAI makes a huge difference, not the case with turbocharged motors.

Many will argue over CAI vs HVI.

WRONG - BMS intake dyno graph vs stock

I mean unless 8WHP and 13WFT/LBS of torque aren't gains of any kind.

Isnt it the other way around?

Intake -> Turbos -> intercooler -> motor

[remydlc]

BMS here. There are gains + plus the turbo's spooling noise is freaking addictive.

+1 on the noise The only thing is I get worse MPG now because I always want to hear my turbos.

This is not true. Hotter air in = hotter air out. This has been proven many times. The IC can only cool so much air.

so true. Sux the way gas prices are going. last time i filled my tank was 3.89 now is sitting at 4.00 and I havent fill it yet, guess when i do it, is gonna be 4.10

Back on topic, to the OP, do a quick search in here or youtube for "BMS intake 335i", and see what we mean.

I mean for $131, including 2-3 days shipping, you CANNOT go wrong.

yep, you are correct.

[raceyBMW]

I will give a +1 to the Logic. And if you get ambitious and want to do more to prevent hot air from getting to the Logic filter, you can build an airbox for it....which I plan on doing soon. I already have some homemade scoops and modified the stock snorkel.

[bimdaddy]

BMS all the way bro. And the freaking sound it makes is awesome. Haven't listened to my music a whole lot lately

[Mr_T]

+1 for the URI.

It may be a few bucks more than the HVI, but 1) looks better 2) offers more performance and 3) it is a "cold" air intake

See post #13

Install was quite easy, so don't let that concern you.

Cold air going into the intercooler will make it more efficient than hot air going into the intercooler...URI delivers ambient temps compared to the others.

Great thread!

[MR5sARECOOL]

has anyone done dyno comparisons?
