It just slays me that people are so quick to deride someone who holds a counter opinion. It's as though the ones who hold their opinion are not sheep. Yeah, right. They've bought into all the anti-K&N propaganda, but, nope, they aren't sheep. They believe it but have never tried it, but, nope, they aren't sheep, just well informed, ovine quadrupeds. Gotta love it. :)
You can usually tell when someone runs out of arguments, they just resort to throwing mud. Or sheep scat. :)
