Good to know, I've always used Honda factory intake filters with good results and the Mobil1 M110A filters. To me, K&N air filters have always provided some amusement, it's simple physics: flow more air, flow more dirt. Air filtration is always a balancing act between restriction & passing particles of a specific size. Honda air filters are a oiled (apparently very lightly) paper design and they test well. Locally, the Fram intake filters cost more than factory, as do the cabin filters. I'm old enough to remember Fram as the "orange can of death", didn't see the logic of protecting a $7,000 engine with a $3 filter. They may have improved, but I'd still go to a Wix product first. Having a long career as a Biomedical Technician and a Gunsmith, I've la few truths: You generally get what you pay for, sometimes less, good and cheap seldom come in the same box. The best rule when it comes to quality: It costs more, buy once, cry once. Locally, the K&N filters are priced higher than the Mobil1. Wasn't aware that the quality had dropped, although I looked at some recently and they were made in Mexico. Hopefully the Mobil1 M110A filters are still decent.
