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

I created this thread because I wanted to see if anyone had any complaints about k & n filters and I haven't heard any. Anyone who has a k & n filter loves it and has no problems. This whole thread is full of arguments about statistics that someone else has claimed. According to that logic then you all should be driving the most fuel efficient, safest, comfortable, highest rated car, therefore with that logic, you should all be driving a Toyota camry (I highly doubt you are!). I was already leaning towards a k & n filter because I loved it in my truck and it didn't screw up the MAF until 60 000 km later. I have cleaned my motorcycle air filters for years without any affect on the engine, a properly cleaned filter is just as good. My usual oil place wants 50$ for every new filter and it's 75$ for a k & n I think I'm going to go with the k & n filter.
