With a snorkle (Jeep?) you can plumb a big dryer vent tube to the front grille. Some have taken air boxes from newer cars and used their air filters
sucking cold air.
I'm old school - I bashed away at my air cleaner housing so it would fit on the throttle body fuel injection.

I used the air cleaner housing and filter that fits it from my '84 Bronco II carbureted V6. Low profile and does not disturb/wrangle the airflow into
the Quadrajet. The snorkel is quite small and could be modified, but in stock form I still have enough power to break traction if I'm not careful on a
wet stoplight corner. So I left it like that. 8)

Wrong
The carb is calibrated for 115F air controlled by the AC AutoThremAC 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.

Multiple posts on other automotive and motorcycle interest lists say the same about K&N filters.

I use the Spectra cone air filters. They are a bit cheaper than K&N and are readily available at Canadian Tire here in the Great White North. I
suspect since they are "performance" they are more about air flow than filtering. However it's rare that I drive the Murray on gravel roads or other
dusty conditions and even then it's not for long... its more about keeping out bugs etc. I have EFI so I have the filter out front just behind the
driver's side headlight.
I've been replacing them every 3rd year, or about 10k miles. That's much more often than my daily drivers which I put on just under 100K in 2 or 3
years only changing the oil, then I trade them.
So if you are like me and only pavement miles then I don't know if the most tight and perfect filtering is really needed.

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.

For my Cadillac engine I am using a stock 1976 EFI air cleaner, with a Wix brand filter. Between the size of the snorkel, and size of the cleaning
element, and considering the RPM's the we run, I see no need to look for anything better. Stock units designed by GM should be more than adequate to
do the job. JMHO

Did you know that Caterpillar, Cummins and other engine manufactures sent
out a bulletin that stated they will not honor warranty if the engine is
using the K & N air filter.
The reason is that it works on a very old and inefficient technology.
Does not mater how much oil you coat it, the media is way too open.
Too much particulates get through and those are dirt and it wears the
engine parts.
We used them when we drag raced and dirt trail as it is capable of
accepting a large load of dirt as the dirt does get drawn in past the media
and go into the engine where most people never see.
