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.

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.

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.

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.

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.

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.

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"

K&N also makes a washable cabin air filter, although it’s a b@$&; 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.

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.
