Review on 🍃 ACDelco Gold CF3213C Cabin Air Filter: Enhancing Cabin Air Quality and Freshness! by Greg Harris

Poor fit compared to other brands (but they were the right size for my 2008 535xi despite other reviews). They also seemed to give off an odd smell for the first day or two after installation. Not recommended, I'm going back to the original equipment manufacturer. Edit: The odd smell persists to the point where it becomes unbearable. It was definitely the filters. I replaced them with the brand I used before and all is good. I have no idea how activated carbon filters can smell, but this is a poor quality product.
