It was $100 for the BMW cabin filter. After 20 min of trying to squeeze in to do it, I would say, that $90 was worth it for the cabin air filter.

Pros: worth the money
Cons: difficult to replace
Vehicle: BMW

I've found K&N cabin filters are great as for the rest you need to run quality, especially your air filter since there are several bulletins about them and they changed the part because of P0299 popping up a lot.

Pros: K&N cabin filters are great

I can tell you for sure the K&N flows better. the new stock filter definitely made me crank the knob up for more fan speed. the flip side is that the K&N does NOT do a good job actually filtering anything the size of sand or smaller. you will also be able to smell every molecule of exhaust and exterior air using the the K&N. stock filter helps reduce the scent of "outside"

Pros: flows better, good velocity and flow
Cons: poor filtration, smell exhaust/exterior air

I changed the micro filter, cabin filter, etc.. The smell seems to be strongest with heat set to 78 and when I am slowing down or coming to a stop and the auto engine shut off turns on and off.

Cons: smell getting worse
