Hi Guys,

Was looking into getting intakes (no front mounts), I have narrowed it down to MST or BMS. Has anyone used either/or?
Does one sound better then the other?
Better performance?
Any feedback would be greatly appreciated.

Thanks Again

Did my research on this a month or so ago. Ended up going BMS non front mount as I preferred:
a. the larger cone size
b. the blue cones

Aesthetically I find it more attractive than the MST setup. Pro's for MST are the heat shields. I will be installing the intakes this weekend, so admittedly still no first hand experience... But my line of logic none the less.

Don't expect any additional performance from intakes that you can't already get out of just swapping filters. Get the BMCs and call it a day.

I am new at this so sorry if this doesn't make sense..lol

Do you think the heat shields on MST give a colder air flow? Or it doesn't make a difference.

Tom, you say no dfference them OEM filters so you don't recommend? Should I stay with the OEM ones?

Thanks again for info

Let me know how it goes and sounds!!!

BMS makes drop in filters also and has dynos posted. Around 8whp gains vs around 18whp gains with the BMS intake.

to each their own, @tom. Constructively, one must acknowledge that 95% of us buying these units are doing so for added induction noise. I've done business with you, but think your statement is as one sided as me saying that the BMC drop in filters sound like crap

I would def say that the reason they (heat shields) are there is to be able to report / support cooler air temps as its a barrier from the bay.... Counter argument is that on FI cars AITs have been proven, even on this platform not to change much from one approach to another.

With all of the active ducting, and added air draw exposure from the wheel wells... I at least concluded the heat shield did not win out over larger BMS cones and overall aesthetics of the set up. When I opened the box I was quite excited. Its a sexy simplistic piece of piping and filter.

I just like how the MST intakes look. The BMS intakes while having larger filters do not look great shoved into the stock box especially with no ram air coming from the front grill. I paid extra just to remove the stock boxes but I'm okay with that.

All good, it's your money.

The airbox bottoms are retained for their cold air ducting and heat isolation. Not as pretty perhaps but more functional.

Cold air ducting? The airboxes have no forced air effect unlike F8x. The horns just exit behind the bumper cover. MST at least pulls from the area eventuri pulls from under the headlight and from the fender liner. Not trying to start an argument here but both of those points are moot.

The air behind the bumper cover is pressurized by the vehicle in motion which is why the factory pulls from that location.

I went with BMS since I've heard from multiple people now that BMS is louder than MST. Dyno results have shown gain in HP with the intakes so doesn't look like heatshield is a concern. Plus I like the looks of the blue filters.

[TexasEd]

I have BMS and am happy with them. Not expensive, easy to install, and slight power boost.

I really do wonder if the Front Mounted BMS create more air resistance than the OEM. I have them and the only downside is the semi rough idle, is not really bad, but it's noticeable under cold weather.

For one of the turbos, the tube is really long and weird shaped, I really don't know if that would create turbulence, either way, would this be even noticeable?

I may go back to stock and collect logs again to see if there is any difference.

Both are good options, I have the MST on my M4, and im very happy with it.

Looks really nice!!

Fit and finish of MST is really nice. Although I did build mine custom when no options were available if I had to do it again MST all the way.

In a water to air or air to air it's always best to have the lowest IAT1 (pre-cooling loop) as possible. The factory setup might have enough headroom on stock boost levels but it gives you more headroom as you increase boost via tune etc. Should always aim to have the coldest air possible into the filter.

So which would you prefer MST or BMS?
