How many are running an air filter and why?

WHN · 11-22-2021, 02:26 PM

I always have used an air filter along with engine side pans.

Keeps big things out of the engine. Never a problem with carburetor settings. Stops flash back from carb to.

Enjoy.

We are RHD so none of the filters you guys use will work except maybe the "Hiboy" one but that can't be used with one of those oil filters on the side cover kits. We have to get creative. I make a fibreglass adaptor to go from carburettor throat, out through the gap between the choke rod and the column itself, then upwards. A short length of old vacuum cleaner hose connects that to a paper element filter mounted on the radiator stays. It is tight, tight, tight in there so it can take a lot of fiddling to get it right. As I have said before, The Model A is very poorly designed for RHD - there are so many simple and cheap ways it could have been improved on the drawing board.

I also use an original aftermarket AirMaze. It collects a lot of dirt so must be doing something. Does not affect the fuel mixture at all that I can notice.

My Weber carb for a Model A came with an air filter. Therefore, it was jetted to run with one.

If I was running a stock carb, not sure what I would do.

I use a K&N highboy setup and like it. As for whether to use a filter or not - the jury is in - filter. Sucking in abrasive particles and damaging cylinder walls of our cherished engines would be unwise.

Back in the 1980s I ran a K&N type air filter in my 68C....seemed like small price to pay to keep the large particles out of the engine....never any problems over the several years I used it.

CarlG · 11-23-2021, 12:38 PM

I use a K&N filter on my Stromberg 97 because my engine builder said so.

Synchro909 · 11-23-2021, 12:47 PM

I run the filter setup outlined in post #5 for longevity of the engine. I often drive in dusty conditions and don't feel like paying for another rebuild any sooner than absolutely necessary.

I have an air filter on my carb in the past. Took the pleated paper element out, and used that cage with a length of paper pleated furnace filter in between the cages. low reisteance... I have not yet fitted it onto the new engine.

My Weber down draft comes with a filter. The carburetor compensates for any added air resistance. It is mounted up high out of the way of rocks and dust kicked up by the tires. I just replace the old filter element which was dirty.

Ivan in southeast va. · 11-24-2021, 04:05 PM

I took the filter off but left the curved pipe that points down on. Unrestricted and pointing down for safety.

Air filter cause problems when used on Model A's, if you are hell bent on using something...make that something an air maze.

old ugly · 11-24-2021, 06:23 PM

i run an air cleaner because it keeps the dirt out of the engine.
do you have an air cleaner on you modern car?

I can guess but I'm not sure I know exactly what an air maze is. I'm expecting it is some air cleaner that suits only LHD cars and that's why I haven't seen one.

Air maze was an original aftermarket accessory that everybody seems to remember simply because the design was duplicated many times over the years. There was probably some different designs in the era, might be in the unauthorized accessories book.
