On top of that when they are freshly cleaned they allow through more dirt not less. Over time the dirt and dust that builds up on them traps smaller particulate matter. You also don't change the filter more often, you don't change it at all, you clean and re-oil a K&N filter.

Way to resurrect a thread to answer a question with total misinformation. Literally everything you said is incorrect except that this is an old thread.
I agree with what you say, when you market well, you can sell just about anything you want to anybody you want. Actually, I've had that junk in my Nissan for about 11 years. But I would never put it in the 335i. Never.
