Would like to go with an aftermarket air cleaner that I won't need to mortgage the house. I know it needs to be low profile. Or is just a K&N element enough?

The thin hat adaptor from the Grand Cherokee V8 can be made to fit but it interferes with the airflow into the Quadrajet and makes it almost unusable.

Wrong
The carb is calibrated for 115F air controlled by the AC AutoThermAC system. This allows the leaner calibration to still be drivable with better fuel atomization in normal driving. Under heavy throttle the vacuum goes away and it sends cold air to carb for max power Poorer full atomization dilutes the oil, wastes gas and wears out engine faster. .

As to the K&N 'cones' I follow Jimmy the K's advice which is they're for chit. In that his engineering background is in fact in filtering air I suspect he knows what he's talking about.

K&N might be ok out of the box. But forget about lifetime. Unless you have a science lab there is no way to properly reoil them evenly and cover every pore. Too much it's restrictive and can foul MAF sensors if equipt Not enough and basically only stops rocks and bugs, not abrasive dust.

Very hard to improve the ability of the OEM air cleaner. But, if you are
converting to EFI, it moves the air cleaner back so that it interferes with
both the HEI and Cruise control diaphram. Your choices are to beat the
metal can into submission, or seek aftermarket parts that kinda fit. When I
convert a coach, I use the Turbonetics adapter, followed by a convoluted
neoprene hose connected to a piece of 3" I.D. Stainless Exhaust tubing.
Where you go from there depends upon the year model of your coach. Early
coaches only have tubes that support the front body to frame mount
structure, and later coaches have an "impact extrusion" (stamped steel)
strut that blocks a clear path to the front of the coach. Also, some have
chosen to install additional battery trays there that occupy the space for
a good air cleaner. Jim K. has an excellent kit for a remote air cleaner
that has most of everything you will need. Look there first and see if it
will work for you, if not, Y.O.Y.O. My last choice would be a K & N. They
do not filter out the fine stuff that wears rings and cylinder bores.

A properly maintained k&n filter can work just fine. The oil is colored red
and the paper filament is near white when properly cleaned. If you follow
the directions and oil the filter properly it is pretty easy to visually
inspect the filter to see if it is properly oiled by noting the color. I
ran one on my 7.3 power ai for 260 plus thousand miles in very unforgiving
terrain and never saw particulates accumulating down stream where I oiled
the continuation of the pipe towards the motor. I also never had any engine
troubles which could be linked to dirty intake air.
I also ran one on The War Pig but did not put enough miles or years on it
to see how well it performed. That said, you will have a notable increase
in engine noise as the factory air filter tin is better at muffling the
sound of the intake charge.
