I am getting a performance intake for my 2016 5.0 F150 from JLT. The filter is an S&B dry conical filter. Their efficiency ratings look great. I am adding a prefilter to it as well to try and keep it cleaner longer. Now S&B and JLT both say that you can clean it out by tapping it or using compressed air from the inside out to extend the life of the filter. I thought that this was bad as it would make “bigger holes” for more dirt to get through. What are your thoughts on this?
