Pretty sure I told you before, but maybe not, or you didn't believe me. Its not an issue . How do you do it from above, and then think it about it for a moment, its the same from below, you reach down, and I reach up
I have no idea why you ,and Cummins even question which way we do it, you guys made it clear what way you do it, and will continue. My point has always been that I have done it thru the top removing the air intake, it sucks, you can minimize it all you want ,don't care.
I prefer the fender well .
Apparently you have not removed the filter from the bottom, and don't intend to , why not just move on. You are not going to convince someone that has tried it both ways, and prefers thru the fender well .
