There's so much controversy about this issue that I don't know what to believe anymore. That's why I figured not to take the chance and consider using a paper filter.

But then I watched those videos on the k&n site and saw how much experimentation they went through to prove that the oil would not come off... now I'm not stupid and I know they would only publish media that would promote their product. And although it looked very convincing, I wouldn't be surprised if the experiments were rigged, or if negative results were filtered out (mind the pun!).

But still.... I think they have a point.
