Reviews of Purflux oil filter

I used purflux on my Passat

Filter is mostly made by Purflux.

What is important is the filter. You want to stick to OEM, genuine mini or from Purflux. This isn't so much a brand quality thing as it is the zig zag pattern matters. It allows for a larger surface area in a smaller package, and using a same size straight fin filter that does filter just as well will still result in suboptimal flow because its surface area isn't the same, all geometry. There are oil filters like K&N that claim to be higher flow, but they're still straight finned and accomplish the better flow simply by filtering worse
