Cabin filter Tesla or Bosch
There's no point in getting an aftermarket engine filter, just get OEM and don't worry about it any further. In all likelihood, Wix or Purolator make okay substitutes, but they're no better and not really cheaper. K&N is going to do a bad job of actual filtration and just get oil up in places you don't want it; they're garbage so at the very least don't get one of those. Stick with OEM.
The "best" cabin filter depends on whether you want any specific features like carbon granules or HEPA filtration. I do want HEPA filtration, so I use the Bosch 6092C cabin filter, but it does have the downside of reducing airflow somewhat (and of course you'll probably need to change it more often.
Pros: good filtration
Cons: reduced airflow
Part number: 6092C
I've just hit 40k km on my car. Only brought it in once to change the cabin air filter.
Pros: minimal maintenance
Mileage: 40000 km
‘21 Tesla Model Y, I’ve needed an air filter change with coil cleaning, another coil cleaning I did myself. Set of tires at 25k miles. Currently at 30 k miles and only other thing I’ve done is refill windshield washer fluid.
Pros: minimal maintenance
Mileage: 30000 km
I’ve changed the oil in my Tesla zero times in 15k miles, but I did have to replace the windshield wipers, and cabin air filter.
Pros: no oil changes needed
Mileage: 15000 km
Replaced cabin air filter with high efficiency particulate-air (HEPA), Bosch 6037C. (The Bosch and Amazon websites only say it fits the 2020 model year, but it was fine.)
Pros: fit fine
Part number: 6037C
Just picked up our second Model Y, had our first one for over a year and 20k+ miles and the only things it needed was tires (put new wheels and tires on), and cabin air filters change (took about 15 minute in my driveway).
Pros: easy cabin air filter change
Mileage: 32000 km
This is my Cabin air filter after 14k miles and 1.3 years. (Supposed to change at 12k miles according to BOSH, so I'm not TOO far past the schedule, but you can see that it is working at filtering stuff out of the air and a change is needed...) I'm using the upgraded Bosch Automotive 6078 HEPA Cabin Air Filter for $11 from Amazon because I have seasonal allergies and want the extra HEPA filtering, an OEM filter may not pick up as much stuff / may last longer?
Pros: good filtering, HEPA
Mileage: 14000 km
Part number: 6078
Bought a Bosch cabin air filter for $13.39 and a Ecogard engine air filter for $13.52 from Amazon. Installed both today in less than 5 minutes. Super easy just check a YouTube video.
Pros: easy installation
Vehicle:
Mazda
Every 6 months to a year you need to replace the cabin filter and clean the evaporator.
Pros: preventative maintenance
Cons: a bit of pain
I would not use the Bosch one again. 1) It has a chemical smell out of the box that needs time to dissipate 2) it restricts airflow... that's how it's a HEPA filter 3) Bosch isn't kidding about its replacement interval, when it gets plugged up (and it's fast) you get no airflow.
Cons: restricts airflow, chemical smell
