Being a guy from the old school, I'll just post some thoughts. I've seen some of these KN filters with no requirement of oil saturation. They are supposed to boost air intake. How do they do that you may ask. There is another thread that follows a spectographic analysis of oil with a KN filter and shows high contamination. It could be that the extra air comes from a reduced micron rating of the air filter. I know KN filters come from racing where the engines are TORN DOWN AFTER 500 MILES. I suppose you could do that. Oiling the filter is what you do to lawn mowers. Is you car a lawn mower? Soeone here has used KN filters for 10 years, but how much driving does he do, and what is the real condition of his engines. Car mfgs have designed air filters to keep ring and cylinder wall wearing grit out of the engine. I think they know what they are doing. Do you think they would miss an opportunity to increase power if they could just change the air filter design? I'm sticking with a good quality stock air filter and get another 300,000 miles on my car. If your rings get ground to nothing by partially filtered air, how are you going to prove that it was that racing style air filter that caused the excessive blowby and oil consumption. Meanwhile the after market mfgs are banking your money while you try to figure out how to pay for an engine. That's just my take as a 30 year professional MB mechanic.
