I've been running these K&N Pods for nearly a decade and once I learned how to properly install them I had very few problems. I haven't gone to great lengths, no inserts, no special clamps or anything. The safety wire isn't that hard to do.
Also, these filters are technically a little snug by 1 or 2mm. Doesn't sound like a lot but it amounts to them wanting to pop off if you don't do it right.
