Cabin filter Tesla or K&N
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
125k miles on my 2020. It's been flawless. Just normal maintenance like tires, cabin filter, and brake fluid. Been to Tesla service center for two precautionary recalls.
In terms of build quality one tweeter speaker got lose which caused a rattle that I was able to fix, and I sometimes get a rattle from the passenger side B pillar, otherwise everything else has been great.
I've lost maybe 10-12ish miles of range due to degradation, most of that happened in the first two years, I've haven't seen it degrade any further in years.
Honestly one of the best cars I've owned.
Pros: flawless, normal maintenance
Cons: tweeter speaker got lose
Mileage: 201168 km
2019 m3 rwd lr with 40k gets 278 at 100%. Rated 310 new. Sits out in the sw fl sun 24/7. Maintenance has been 1 set of tires, a new 12v, cabin filter swap, and wiper fluid. We still love it.
Pros: still love it
Mileage: 40000 km
I changed cabin air filter on my Model S few weeks ago after 70k km and to my surprise it was clean like it was there for only a month.
Pros: very clean after 70k km
Mileage: 70000 km
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 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
K&N also makes a washable cabin air filter, although it’s a b@$&; to clean.
Pros: washable air filter
Cons: difficult to clean
Don’t get the ones with the carbon in them, buy OEM. The reason is these restrict air flow which is harder on your AC system and testing shows they do a worse job of filtration as well.
Pros: OEM filters better
Cons: restrict air flow, worse filtration
I had these and they created mold also. The oem filters without the "active charcoal" are much better than these and they are cured against mold.
Pros: OEM filters better, cured against mold
Cons: created mold
