Well I decided to clean my air filer after having it on for about 8 months and never showing any signs of being pluged on the indicator. Was suprised at how heavy the filter was so I weighed it and then washed it. After letting it dry and reoiling it I weighed it again and the filter had lost 2.8 lbs. When I put the filter back in I checked the itake piping and turbo and there was no dirt or oil any where. Very impressed with this filter. Just wish the other Banks products I have tested were this good.
PS. this filter had seen hundreds of miles on dirt roads here in the oilfield.
