Just wondering thou... unless oem filters are made out of brick. How is a different airbox design with bigger volume helps with more power on a force induction setup when turbine and inlet/outlet to engine hasn't change.

For the same cost, I would think a down pipe to exit exhaust faster would be more efficient at getting more power out of the F10 M5.

But the cf looks great nevertheless. Congrats and enjoy!

It's good for those M5 owners who love to pop their hood everywhere they go.

I've heard chinese knock-off company is about to start production on them...lol

Very nice! Look forward to more updates. I don't think current F10 M5 owners car about the cost. It's about the aesthetics under the hood.

The price for this should be 400-500. It's just two filters ands some small CF pieces. They're charging that much cause you drive a new BMW M5.

That is one of the premises that the aftermarket sector uses to set their prices, the supposed wealth of prestige car owners. I wish I were one of them, but I'm having to struggle to put this M5 into my garage. I bought my first BMW in 1969, a 2002 model which cost $3,600 brand new!! Just slightly more than the intake from GruppeM with some bits of carbon fiber and two K&N filters....... Makes us older types a little less tolerant of the prices these aftermarket companies foist on us. It seems they think we're stupid as well. If you value the looks of your engine bay enough to spend thousands of dollars with no appreciable gain in horsepower, who am I to say no? If I had the extra money with no better use for it, I'd do the same, it is a good looking system.

You're talking about ducted air into an air box and then into a forced induction engine. Quite simply, it's not ram air. Ram air would imply that you are pressurizing the intake into the engine over atmospheric. Simply, you're providing more air in the intake than the engine (which is nothing more than a fuel / air pump) can pull through at any given RPM and load.

You're not doing that with forced induction. THe pressure in the intake manifold is a function of the turbo and the associated controls (ECU, waste gate, etc.) only. Not the intake. The only thing this intake (or any other intake on a forced induction engine) could possibly do is eliminate vacuum in the intake pre-turbo. That's it. Whether or not that's worth power depends on whether or not the vacuum in the intake prevents the turbo from making maximum boost at the target airflow for the given RPM / load. Vacuum in the intake is bad, but it's not guaranteed to restrict power.

Cool intake, but those gains are hard to believe, even with an engine moving this much air. In order to make that much more power, the stock air filters must be VERY restrictive.

This response was posted by Sean@PSI on 6-20-2012
To clarify, the RAM AIR name carries over from their line of intakes for all types of engines, including N/A and forced induction. To be more specific, it is the name of the specific product line from GruppeM and nothing else.

The Dyno was from a Dynapack system in Japan. Once we receive the intake stateside, we can have some more tests done with a more familiar dyno system, such as a DYNOJET or a MUSTANG Dyno to alleviate any doubts or concerns.

My reply:
When comparing the K&N filter to the stock filter, which do you think has more surface area to pass incoming air? Given that the stock filter is more restrictive per square inch (just a guess), I believe there is still so much more area that it will flow more air than the K&N. The sales pitch mentions "heat shielding carbon fiber". How long do you think the air is in the intake tract before it gets to the turbo? Do you think there would be much chance for a significant temp increase from ambient in the stock system? The GruppeM system is very attractive and I think that's what they're selling. Has anyone done an on the road, side by side test of a stock M5 and a GruppeM equipped M5 to see if there is a performance difference? It's been five months since the GruppeM system has been available in the USA, someone must have by now...? I'd think with the GruppeM carbon fiber additions to guide more air into the intake snorkels, a test in a moving vehicle would be even more advantageous for them compared to a dyno. For the retail price of $3,500 there had better be some advantage, but I don't think there will be. I have great respect for IND and their work, and I hope they will do their own independent test to confirm there is a measurable increase in performance. I'd hate to see their efforts minimized by an "upgrade" that really wasn't. Much more performance gain to be had on the exhaust end with a turbo motor than on the intake.
+1 I am glad you said this. I am calling 100% BS on this "mod" and its claims. I not only call BS on the gains, but I actually am willing to put money on it that this intake actually REDUCES power. That's right--reduces.

There's no gains to be had on a turbo charged car (or any car for that matter) with a well-designed airbox. Considering the M5 comes with TWO airboxes that already move WAAAAAY more air then needed, the claims this intake is making is ridiculous. It's evident in the way the advertisement/thread is worded. Cheesy wording.

These guys tested something similar:

It's a Made in Japan company, therefore their "Engrish" advertisment wording probably won't be spot on and the cheesiness as well as the word extravagance will be piled on.

Consumers should definitely do their research when buying a part but ultimately what aspects the customer is really looking for (i.e. looks or sound increase over appreciable power gains) will come in to play. On a side note, several owners have noted an increase in throttle response and of course intake noise. The reduction or elimination of baffles and such in the stock air box maybe played a role in this?

Looks like 12WHP & 8WTQ from Gruppe M Intake @ 1:18 into the video.
Big thanks to EAS and IND for doing this!

But it looks so FN HOT!!! Some tuners offer ECU upgrade for 3.5k with 80HP 100nm increase.. So the question is : Looks or power??

Looks great but i dont pop my hood when I go hang out somewhere so it's not a mod I would consider. Im going with the BMC filters and maybe someone one day will produce airscoops behind the grill or something of the sort, similar to what RPI did for the E60/E92 systems. Thats about as far as I would take this. I do get it though. Looks great and Im sure it sounds cool too.

I was told that rpi is testing/design some air scoops along with bmc filters, but have not informed everyone yet until they have not finished.
