Used K&N filters for 10 years on my offroad vehicles. The K&Ns needed a pre-filter which was womens panty hose wrapped around the filter to prevent clogging up too soon due to dirts affinity to oil.
That common backyard fix spawned a whole new company just making pre filters, first for K&Ns then for other filters. Outerwears pre filters. Then determined vibration and rough action of offroading broke down oiled gauze over time.
Now for the last 25 years I have used oiled foam filters with outerwears pre filters. This has proved to be the longest lasting and best compromise of air filtering and performance. Outerwears shakes off the dirt and the oiled foam does not break down from vibration and the repeated washing and re-oiling. YMMV
