First thing I did when I test fitted various filters. I did the same on our RRSC and a 5.14% increase in output which yielded a 26.6whp return however when paired with K&N filter there was a very unpleasant unwinding sound from the SC in certain conditions or settings. Nothing obnoxious but noticeable to the sensitive ear but tolerable since the engine whine and note improved dramatically at WOT.

I know there's been a couple pics of the filters, but I thought I'd throw a couple up, too. Pics are always good.



I find this funny...


Also, just a quick note for those that might decide to remove these while waiting on the BMC...or slow-a$$ K&N...the removal of these is super simple and I would rate it 1/4 beer, in difficulty.

For those, also, that may not be the best at wrenching, don't be afraid of this quick mod. All you need is a Torx bit and a driver or a one-piece Torx screwdriver...and a small pry tool (I used a standard flat head screwdriver).

Start by removing the engine cover, then look for the screws holding the two pieces of the airbox together. Using your Torx driver, start backing out those screws. Note, once the initial resistance of the screw is over, it will get easier to back out UNTIL you start to feel resistance a second time. Give it one more full turn and stop. There is no need to remove the screw completely! The second resistance is it backing out of the top half of the airbox "sandwich". Backing them all the way out could lead to a lost screw. After you back out all screws, use the pry tool and work it under the edge of the charcoal filter that is snapped in place on the underside of the top half. Pop it out, and move on to the next side.

Also note, there is one PITA screw located on the driver side, front left. Its situated behind a harness plug and a bit difficult to see and get to...just FYI.

I know this mod for us gearheads is a no brainer, but as an Admin for another forum, there are always those that suffer from anxiety on these sorts of things...and are equally anxious about asking for help for fear of flaming. Every little bit helps.

I wonder what markets have the carbon filters installed? I know this was a topic when I had my 2013 X6M. I attempted to remove them, but discovered I didn't have them. In Canada we did not have them installed from the factory. Anyone know if the carbon filters are installed in Canadian spec vehicles for MY 2021?

I took these bad boys off as well. It snowed today, so I wasnt able to test the difference, but based on my butt dyno first impressions, car feels about the same as before.

Took less than 10 minutes from opening to closing the hood. Total of 12 screws on both sides after you remove the engine cover.

I've not tested mine yet, either, but I was thinking you won't feel much except in the higher RPM range, where boost is paramount. Supposedly, it should sound a bit better at lower RPM, though.

It's was in my MY2020, so yes.

Maybe it's a conspiracy and BMW is simply trying to reduce the power of the car so that they don't get too close to the X5M

Odd, the 2013 X5M I owned had them but E70 48i did not... The F15 50i and the F85 X5M I had did not have them either but this G05 M50i has them however my X7 does not. Not sure what the parameters are but I suspect that it may have more to do with the location of the filter in relation to the IM and or the piping leading to. Only guessing, I really do not know.

As funny as that is..... there is a HIGH degree of truth to that

Stock X5M competition: 625 hp
Stock X5M50i: 530 hp

Stock X5M Comp w/ tune: 700 hp
Stock X5M50i w/ tune: 700 hp

While I'm sure the X5M guys will tell you about every single internal engine component that differs between the two engines (and there are a few, admittedly), they are essentially very similar to one another. The X5M50i is just heavily "detuned" from the factory.

Agree. Essentially, you can get a tune from BMW from the start or a 3rd party, later. Either way, max HP should be the same. 95% (or more) or the wo engines are identical.

The X5M has a few internal engine components that are forged, that allow the engine to rev a bit higher. I believe there area few other minor differences as well.

But otherwise.... yes. Both of them "fully tuned" within the ECUs parameters, and the restrictions of the exhaust, etc..... will end up producing the exact same power.

Same size engine, same size fuel injectors,.and I believe they even use the same turbochargers (I'd need to look that up though).

I don't disagree one bit. This is exactly why I went with the M50i (and typically go with BMW V8s over I6s) - it's the perfect mix of luxury and sport with a huge upside without spending 10s of thousands.

While X5M owners may tell you "it's not a real M", I'd venture to say that M50i owners drive their cars harder and are more likely to take it to a track rather than someone just shopping for a badge - so they majority of them will never see a real benefit in a "real M" SUV/SAV anyway.

Also, keep in mind that with a Carbahn tune on the M50i, you make SIGNIFICANTLY more power and more importantly a lot more toruqe than an X5MC and still have the warranty without having to hide it from BMW for $2,500.

Leaving out all the supporting hardware revisions changes and upgrades. It is more than just output. Anyone can squeeze power out of a turbo motor but not everyone installs all the items that are supposed to accompany the increased output. None of which is an air-filter alone.

Look at the myriad of differences between the F15 and F85:

Hmm, maybe the reason they left it off the X7 is for it to be a little closer to the X5 M50i due to the additional weight. Afterall, I'm sure BMW does not want their top of the line SUV to be much slower than the smaller sibling.

It is an emissions part not performance related however it does effect output. Perhaps the routing of the plumbing and the different orientation of the air boxes has something to do with it.

I assumed both engines are very similar. It seems that's not the case, perhaps.

I understand that BMW would put better quality parts in certain high use areas because the M has more of a chance of being tracked as opposed to the M50i variant, but do you think it's that much difference?

I just assumed that, for the most part, these two engines were virtually indistinguable...just different mapping. I also assumed the $20K premium to the M was mostly about the suspension and interior upgrades. Engine components get expensive real quick. Plus, the extra R&D to have 2 similar engines, but with different alloys for parts. Just sounds cost ineffective.

But, I'll freely admit that this is my first BMW. Maybe that's just their way.

Also, if I were to tune my X6, it would not be for tracking it. It would be for the 3-4 times a year I need to see how fast I can get from red-light to red-light. Or take down the redneck trying to show me up in his 1997 F-150, lol.

Surely, the lesser spec'd innards could handle that, right?

Depends on one's definition of "that"; to my wife it is "different bumpers and seats are not worth the premium". Having owned every version of the X5 since it's debut (except diesel and hybrid) I notice the difference but rarely ever utilized it.

I don't think 99% of people will ever be "tracking" an SUV or SAV. The biggest differentiator will be straight line performance and the badge.

Considering that you can't even get the X5M with the 2 axle air suspension, it probably makes even less sense for most people.

Here's a great recent article I read on the M550i. I think this applies even more for an SUV.

Yeah, I think it was Car and Driver that did an article on the 2020 X6 M50i and they declared it was "just the right amount of M". I agree.

It's civilized when you need it, but a beast when you want it!
