Soon-to-be 2021 Model 3 SR+ owner here. Whenever I search for accessories for the M3, air intake filters or guards always come up. Is there an issue with air intake with the Model 3? Is it ok to add an aftermarket air filter? Strain on the a/c fan? Does Tesla suggest it? It seems to be one of the most talked about accessories but I cannot seem to find a lot of info on why.
