PS Oiled filters have a much bigger issue on naturally aspirated engines than turbos. Has to do with getting the MAF sensors coated with oil thereby reducing their sensitivity.
A lot of turbo engines do not have a MAF (speed density using pressure sensors instead). So far, the MB turbo V8 engines have been using a pressure sensor and no MAFs, not sure about this 4.0 though

Agreed
my Personal experience in the past running K&N filters was that my turbos got oil on them and While I’ve never had a warranty issue, I’ve heard of other people that have had issues with turbo impellers covered in oil causing warranty issues.

Not saying this is not possible, but I can bet the oil had a lot more to do with the PCV blowing oil into the combustion chamber than the filter

Not sure how they can be selling these if BMC are not making them yet?!!!
They are having issues with the mold. I believe its still a couple of weeks away.

I don’t think most anyone racing, or looking to tune and maximize performance would be running stock air filters on any turbo or non-turbo motor. The filter itself usually doesn’t give you any noticeable improvement in responsiveness, but in combination with an aggressive tune and free flowing exhaust, filters are at the very least an essential building block of a more responsive, and yes, usually a better sounding drivetrain. These stock filters look to be very restrictive, so when I can source for something less that Renntech’s $360 price, its an automatic mod.

There is nothing to be gained with these high [less filtering] flow filters but more wear on turbo blades.
Come on guys you are buying into the aftermarket AMG tax with nothing to gain but turbo wear..
Unless there is real proof that they flow and "filter" better save your money.

my responses earlier in this thread agree. However I primarily look for these dry filters as permanent and they tend to save me money long term and if they flow better than so be it. I have had a set previously that were proven with dyno results. Oiled filters are generally not a good thing anymore. Otherwise factory would be as well. Cheers

But it sounds better. All seriousness. Even if it only adds 0.0001 HP it does sound better and for the cost it’s literally the cheapest mod you can do to your car that actually has a measurable outcome “even if it’s only your ears”. In a world where you buy a 12k titanium exhausts that adds 0HP but drops the same amount of weight that you and your conpilot added at your local Mickey D’s. The $235 air filters seems to be a steal. 2 cents and yes I spent way to much on my exhaust for my Cayenne Turbo. #onceuponalife

To each their own but putting a BMC, K&N or any of the cotton filters available in the market is one thing I personally will never install in any of my cars. I have enough experience with them to know that unless you clean them regularly, you will have grit and particles big enough to accelerate wear to your turbos/engine. I say regularly as in every few hundred miles. Even then, if you're in a dusty environment, you will have grit getting though. I do run a BMC filter in my race bike and I clean it after each day of use. This is maybe a couple hours of actual use on the track and I sometimes see bits of grit specs here and there inside the airbox. The only reason I keep it in there is because my engine and intake is set-up for it. Otherwise, I would rather use the OEM filter. Improving flow does not necessarily mean better performance. Like exhaust needs scavenging, the airbox need it's equivalent and the engineers have spent a lot of time and money to get the most out of the intake systems with minimal loss in filtering (protecting the engine). On a forced induction system like our E63s, it wouldn't surprise me if there was barely any gained in performance if any. I'm not one to judge anyone for doing something just for looks or sound but just understand the risks with cotton air filters.

While I am inclined to agree with you...

My experiences have been the opposite. I have seen the factory filter for my car and it’s a giant paper filter with a giant foam mess glued to it. I have removed my filters for cleaning 1-2x per year depending and I’ve never seen anything on the engine side of my air intakes. Ever.

For those that interested, below is a good read. There are links at the bottom with his flow and filtration tests:
