I find there's enough 'flex' in the air intake pipe to allow the filter to pass between air conditioning pipe and intake pipe to bring used filter up and new filter down between the two. (Works on my 04 LB7 - may or may not be the case for newer engine configuration.)
I coat the big 'O' ring for top seal with a very SMALL amount of grease so it sticks in the top O ring groove of the filter. Without that it has a tendency to 'pop out' of groove. I cover the top of the new filter with Saran or cling wrap as I manoever it into position. When in position I pull off the cling wrap - check that O ring is still in right place - lift it onto the filter housing and start turning it.
The key for me is to get both hands down to the filter, and that allows one hand to provide the upward pressure required to get the filter neoprene centre 'doughnut' seal onto the nub of the filter housing and the threads in position to start turning with the other hand.
Don't overtighten the new filter.
Works for me. Never had a problem yet.
