I've run K&N filters on virtually every motorcycle I've ever had (when I wasn't running UNI). Wash, oil, reinstall. No problems. Long lived engines.
My PT has a K&N panel filter. I hold it up to the sunlight every time I wash it. No perforations even on the high boost 2.4. (high boost = more air drawn through)
I have a friend with a wheel lift Silverado 3500 wrecker. He said that before he put the K&N on, the OEM filter elements would get sucked into the intake. I never actually witnessed the filter wedged into the intake but I don't know why he would lie about that.
For a filter to get sucked in, it either got wet, was a poor fit, or got really clogged.
