Air filter for Model A

[Purdy Swoft]

I'm not a believer in air filters on model A's with updraft carbs. They mostly cause rich operation and cause more problems than they solve. Thats just me though. If you like it, go for it

The last thing that I would want is Gasoline drenched ABS plastic that close to my exhaust.

Agreed. If I drove on mostly dirty roads I might consider

If you are using a filter with the downdraft carbs I would only consider using a filter that is above the carburetor. If you have a small leak and it accumulates into the filter then you have a dangerous hazard with it right next to the exhaust.

If it couldn't be above the carb then I would go without. My opinion.

I agree! Unless you are driving in a sandstorm, what use is the air filter on an updraft carb? Any type of debris that would be substantial enough to damage the engine would be too heavy to be sucked UP past the throttle plate, UP through the vertical part of the intake and then UP through the valve chamber into the cylinder! With the modern fuels and oils now in use, gooey carbon deposits which trapped airborne dust are rare compared to the old days! I am a firm believer in air filters for downdraft carbs! Airborne sand and dirt that would be too dense to enter an updraft carb would be easily ingested by a downdraft carb! I just don't think a Model A needs an air filter unless you are driving in extremely severe conditions! Henry didn't think they were required when most of the roads were gravel and today most roads are paved!
