I need a new air filter, but I don't like the stock one. I like the idea of a k & n filter that I can clean an reuse. I searched a few forums and I didn't find much on k & n filters. If anyone is using k & n filters, what do you think of them? Is there a better aftermarket filter that I can easily gets hold of?
In my truck I used a k & n filter, but the oil from it caused my mass air sensor to malfunction and I had to replace it and ditch the k & n filter. Has anyone seen these problems in the BMW
