Hmmm... I was reading up on the K&N air filter and was leaning towards getting one, and now this post scares me in the other direction. I think on the K&N site I read that if you were told by a service Dept. that the filter caused some kind of damage, that they would write a letter to the service dept. on your behalf and tell them that they are full of it. I don't know about the one you are using. Now I don't know what to do. I'll read the posts on this thread to see if I can be swayed the other direction again!
