I own 4 vehicles including one diesel motorhome. I am always in search for ways to save fuel. I have debated over the years whether to get K& N filters or not. Their ads have been very tempting but I hesitated until now. I don't have all the data from all 4 vehicles yet but my first test vehicle , a 2007 Dodge Ram 2500 Cummins diesel, showed an improvement of fuel mileage from 18.5 to 22.5 miles per gallon. If that is any indicattion of fuel mileage improvement, then I am a happy camper.
