It's the "HAIR MESH" inside, that duz the job:D Should I oil them with K&N filter oil:confused: It smellz pretty GOOD:D
When I bought Minerva, I put an ITTY-BITTY paper filter on her, it FELL off, now resides on the wall, with her 2 Blade Fan & a BIG "S" shaped Railroad Wrench & other DUMB things!

It is up high out of road dust, far away from heated exhaust, & just think, our normal wet flammable gas dripping from our Model A carburetors cannot drip uphill to wet this high filter & cause a very exciting engine compartment fire.

Do "our Model A carburetors" really leak and drip that much. There must be something wrong with mine... :rolleyes::rolleyes:
 
Ever notice every now & then how many Model A owners have engines that never leak oil, carburetors that never leak gas, cooling systems that never leak coolant, tires that never leak air, points that never need adjusting, brakes that always work perfectly without adjustment, speedometers that register within 1/100 mph, head lights that make modern car owners dim their lights, white wall tires that make young women climb on Model A fenders and running boards, piston rings that never leak, and wives and girlfriends that never complain ......... what are we doing to continue to miss the point here ......
 
Here's my final solution- I bought the air cleaner set up from Snyder's that has the 180 degree curve that puts the filter under the carb. After reading the posts about paper air cleaner filaments I decided to do a little modification. I took the paper filter off the new one, removed the 1/4 20 threaded rod and replaced it with a shorter threaded rod. I now have the shorter wire mesh air cleaner mounted to the 180 degree curved piece. No more paper and not up against the exhaust pipe. What type of oil, if any should I treat the wire mesh filament with? Thanks
 
"Maybe" LONG is better? I saw a man whose NOSE hairs were SO long, that they formed an INTEGRAL part of his MUSTACHE!!! And his ears looked like a SPIDERS' nest.

I have never seen a CFM flow rating for the paper filters. My observation has been they tend to restrict the air flow and the engine runs rich.

If you put an air filter on a vehicle that is not rated at the CFM per minute of air flow that the engine requires to run at performance RPM you will have an engine that runs rich and fouls plugs.

I ran my own calculations 12 years ago using the formulas at the K&N see link below, and 200.5 cubic engine running at 2100 rpm and selected a K&N E-3050. To date I have over 30,000 miles using a K&N E-3050 and have never had any fouling of my spark plugs.

Here is a link to the same calculation on Model -A.org. The calculation on the below web site are at an engine running 2800 rpm, and the conclusion is you can use any one of three filters, they conclude any of the three filters below are adequately sized.
◦K&N offers several filters that can be used with the Air Maze housing. ◾Part # E-3050 is 3.5 inches long.
◾Part # E-9257 is 5.5 inches long.
◾Part # E-2040 is 6.625 inches long.
But the site make this recommendation.
“◦To provide some margin for the filter getting dirty, before you get around to cleaning it, I would recommend the 5.5 inch long length. I know it is an over kill, but I am currently using the 6.625 inch long one to allow for driving on dusty gravel roads and to extend my time between filter cleaning / re-oiling cycles.”

The 180 curved filter caught my eye, bought one and thought the single 1/4-20 hex head set screw was not the best way to to hold the unit to the carb. Planned to add two more set screws , but at the last minute I put it on for a local tour. My brand new filter was last seen by the Model A traveling behind me in downtown Nashville being run over by my right rear tire. You may want to re engineer the clamping action!

We can assume you don't have engine pans?? :p:p
