Review on High-Performance PG Cabin Air Filter PC9382, Suitable for 2008-2013 BMW M3 4.0L (Pack of 4) by Adam Martin

They appear to be of good quality at a fraction of the price of the original. I know it seems "cheap" to drive an $80,000 car and then save on parts, but to be honest I wouldn't even consider changing a cabin air filter. Not sure if there is a difference in airflow over time since they are clogged. Anyway, this is one of those parts that I don't mind being "cheap" as I don't see any problems if they don't work 100%. original, such as B. an oil filter. I will buy them again if I feel the need to replace them.
