Here is my intake tube after 7k miles of running the uni. It is/was installed correctly. It is oiled properly. The tube was clean before the install. I will go to Napa sunday and buy the stock paper unit. What a piece of crap this filter is. Those are my finger marks in the heavy dust and sand in the tube. And yes you can see plenty of sun light (small holes) when held up to the sun. Here is shot 2 with the sun shining through a small 2 inch section.
