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
Personally I already changed my stock battery to an AGM and will be installing a washable K&N Cabin Air filter when its next due.
Pros: washable, never replace again
Vehicle:
Kia
To make things easier, I put a K & N cabin filter in so I don’t have to replace it every year. I need to clean it as it’s due.
Pros: reusable, long service interval
Vehicle:
Acura RDX
I put a K&N cabin filter and it's been going strong, wash it out and dry, goes back in and still smells fresh.
Pros: wash it out and dry
I bought a K&N cabin air filter. I wash it in my bath tub. Dry it. Take some spray oil I made myself with essential scented oils, rubbing alcohol, and glycerine. Spray it on. Let it sit for 5 minutes in the sun. Pop right in. Completely fine.
Pros: washable, reusable filter
I just bought a K&N one from work and put it in. Most difficult 2:43 of my life.
Pros: bought from work
Cons: most difficult
Vehicle:
Subaru
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
