Review on 🚗 PG Air Filter PA99230: High-Quality Fit for 2017-20 BMW 330i, 430i Gran Coupe, and 340i Models by Scott King

I changed both the air filter and the cabin filter on the 4 Series. I decided to upgrade to the OEM equivalent of the cabin air filter and wanted a chance to save some money on the air filter. What I can say is that the fit/shape of this filter is perfect and the filter material seems decent if not as good as the OEM maybe. Where I saw the difference was a small piece of styrofoam taped to one corner of the filter. This one is significantly thinner than the OEM I replaced and doesn't adhere very well. So to say it's as good as the OEM would be a lie. But since this filter was half the price of the Mahle, I am satisfied overall. Let's see how it ages and if the brittle piece of foam becomes an issue, if so I'll update my review.
