I have been using K&N filters for years. I have used them as a factory replacement and in the case of my Ducati, as a factory recommended piece of a performance upgrade. For all of the AMG owners, I have used the recommended K&N filters in my 09 CLK550, 07 CLK63, and 08 CLK63. They work as expected in that the factory setup is a grossly restricted paper, plus charcoal and the K&N allows the engine to breathe. The performance increase is perceptible enough to validate the K&N, not to mention the ability to reuse indefinitely. The issue of the oil contaminating the MAF sensor is not factual, more likely user error. I also use them in my 08 Honda and 99 Tahoe. Great product
