Decided to do a quick maintenance item for the car... I've ran exactly 30,000 miles on the original cabin air filter (yes, a little bad) and found one available on Amazon Prime for $20. 2 days and 5 minutes (installation time lol) later, I've got a new filter installed. Below is the comparison old vs new. Size/fitment seems to be spot on, except I don't understand the yellow. Another somewhat unknown point is, that it'd be nice to know exactly how much particulates the OEM vs Aftermarket filter can actually filter. but.. maybe I'm just thinking too much PS... OEM filter was made in Poland, new filter was made in China, but I'm sure a lot of Tesla's sourcing decisions have to do with politics, import duties, parts content when it comes to country of origin, etc.
