Very helpful. Thank you very much. In your candid opinion, do you think replacing the air filter is something any person (i.e., amateur/non-technical person) can do? Or should this be left to experts or those who have some level of experience working on their cars? I do not want to mess anything up, but also do not want to shell out hundreds of dollars for an air filter change. I've watched the videos and it seems like the disconnecting-and-reconnecting the engine access cable seems to be the most difficult part.982-129-620-A has cold protection
982-129-620-B does not.
The cold just has that extra layer on it, otherwise they are identical.
There is no sure way of knowing what is on your car now.
Northern areas get the cold, southern areas get the regular.
In my case (Canada) our cars come with the cold protection, but since I store the car over winter I replaced it with the regular weather filter.
If you don't drive in snowy winter conditions then the B filter is what you want.
Price is the same for both.
