Since this topic usually brings about heated discussions, here are some interesting facts about OEM paper filters vs aftermarket, reusable filters. I know the filters tested were for a Duramax diesel, but no need to try and dis-credit this testing based on that, because the filtering material is the same as used in other air filters. Unfortunately, this test was before the r2c filters were available, so no test info on them.
I’m not posting this to try to convince anyone which filter material is the best. You can read it yourselves, see the proven results, and draw your own conclusions.
