and I was thinking I might install BMC filters in my GTS...

Maybe they didn't forget. Took approx 4 hours chasing down why the LS3 powered 928 had a dead pedal and would barely run, then stall. The Mass Air Flow sensor that sits between the air filter and intake was coated with a thin film of oil. Culprit was the almost new K&N filter (comes pre-oiled). Removed the sensor and sprayed with MAF sensor cleaner and that did the trick. Replaced the K&N with an AFE Pro Dry so this shouldn't happen again. Think I'll stick with the OEM for the 991.02 T

Porsche does this for a living. I'd imagine their R&D budget is probably larger than most third world GDP.

If you start using aftermarket filters with better flow, you should also seriously consider your oil change frequency. In short, more flow = bigger holes= more dirt= more frequent oil changes required.
Go read UOAs of cars with non OE air filters if you are a doubter.

Says they're oiled here. What is the purpose of the oil anyway?
"BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity.
All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit."

Not trying to pick a fight here, as I really have no dog in this race, but cost?
Really? On a car (any Porsche) that retails for upwards of 80k, if not more, a redesigned oil filter (that's lubricated like the ones by BMC or KN) would be what, maybe $$80 more to produce than the OEM factory one? Probably less as the efficiencies of scale would probably make production costs significantly less.
I really don't think even a $100 difference to swap out a redesigned OEM oil filter will be a significant cost issue. For the Porsche consumer that kind of price differential would be more like a "rounding error". Is anyone really not going to buy a 911 because the MSRP is 98,500 versus 98,600?
Obviously, if it works out for you, great. Again, have no dog in this race, but I've just heard too many stories about aftermarket oil filters that are lubed with oil to put much credence in them. Good luck and enjoy the drive.
