This forum is not unique in the ability to figure out why something is fucked up and recommend against it.
True.
Stop blaming the forum for folks pointing out ...
Not 'blaming' the forum; just summarizing its reviews of K&N. OP wants forum feedback on his mods, and I've only ever read negative reviews of K&N on this forum. So, I shared an FYI about this forum members' take on K&N.
I removed my K&N based on posts from this forum. But, to your point, I also could have just checked for dust in my intake tube and throttle body. So, touché.
