Air filter for Model A

Is that the filter that defies the laws of physics by working on "un-balanced" vented carbs? It does look cool.
 
Excellent idea if you plan to drive off road across the desert. At the rate I use my Model A and the roads I drive on it will outlive me so I think I will skip the filter.

Back in the sixties when some of us were driving these as our only vehicles (commuted every weekend from Rochester NY to Utica NY going to college) I don't ever recall seeing an air filter on any of them except for one show winner who had an original Air-Maze on his for shows.
Or is my memory poor ?? Mine had a stainless flex tube between the breather pipe and the carb, but outside of that I just don't recall seeing them. Nor do I ever recall lack of an air filter being a problem, although I suppose the dust and dirt could shorten the life of bearings and rings.
 
I've got an oil bath air cleaner off an old hay baler engine that I put on my 2-door 29 back 43 years ago and works fine but have always wondered if it has the right balance of air. Didn't know about those things back when. I did worry about sucking the oil out of it when I would get up to 70 mph but never had that problem either.
 
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.

K&N air filter, the best filtration with the least restriction. Buy it once; according to K&N service every 50,000 miles. I service mine a little sooner. I am running a K&N on the air maze 90 degree adapter on a Zenith 2. Works great.

One our club members has one he will give away. It will not stay on the carb.
The unit is too heavy and comes loose from the carb. when you hit a bump.

It is held on the carb. by a hose clamp and short piece of radiator hose, that's all. You get a little oil or gas on the joint and you can't keep it on.

I use a K&N E-3050 air filter in an original Airmaze. I have one on my 1931 160B for 30,000 plus miles and also have one on my 1931 68B for 3,000 plus miles. The filter does not cause the engine to run rich and makes a significant improvement on keeping the engine oil cleaner over time. I used to change oil every 500 miles and it was dark and dirty, now I change oil based on color and usually change oil at 1,000 miles or even 1500 miles.

I use an original AirMaze and have no ill performance effects. I drive dusty gravel roads all the time and don't want that grit traveling through my engine.

The oil wetted mesh should grab a lot of dust and not cause any noticeable restriction.
 
I use the "overpriced" High Boy. Bought it on eBay. Cost was cheap when compared to my spare time to play with Model A's ... and I work for free! Add in the gas and wear and tear on my truck to drive to and from Menards and I'm money ahead. I like Rich Falluca and I've given him a small fortune for a couple really good running engines, but I do not want to write another check to AER for a long time. If keeping dirt from being sucked into the carb might keep me away from Skokie a little longer, the filter is a "no brainer," even if Henry didn't think they were necessary.
 
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.

Just bought the filter that "U's" back under the carb. Suppose to be hi flow filter. I haven't received it yet so I'll see how the fit and finish goes.
 
Out of the showroom I thought these 4 cylinder fords had no air filters.
Wasn't the first airfilter introduced on the v8?
I am so confused
