Air filter
This morning somebody in one of the FB Model T groups asked about air filters.
I didn't have a page on the subject, so I made one.

Re: Air filter
Great job Steve!
I recently removed my air filter and re-installed the stock heat pipe for winter driving, but I'll be putting the air filter back on come spring.
I found a vintage Clinton lawn mower filter on Ebay, painted it black, and made an adapter cone out of brass to attach it to the carb inlet.

Re: Air filter
Do you folks running filters find that the intake manifold beyond the carb gets really cold? I have a filter but currently run a heat pipe. I'd like to try it but have concerns about carburetor ice.

Re: Air filter
Tim, you are on to something overlooked in all the above filters.
The most important part of that original pipe is not clean air, it is hot air.
Hot air is required to prevent the center area of that carburetor icing up from the venturi effect for using the air input to suck gas out of the carb bowl.
A carb can ice up on a damp day with the temperature as low as 55 degrees or less.

Re: Air filter
I have not encountered icing (yet), but I definitely get condensation on the intake manifold when I run the filter.

Re: Air filter
So far I haven't been bothered by carburetor ice. I wonder if the combination of warm air from the radiator and engine pans keeping out a lot of the cold air would be the reason. Of course, I'm too much of a sissy to do much cold weather driving anyway.

Re: Air filter
Carburetor ice is most likely to be severe between 50° and 70° F when the humidity is above 60%. Airplanes have a control that lets you bypass the filter and duct hot air into the carb when that happens. I've experienced icing a number of times over the years usually in the spring or fall.

Re: Air filter
If you do it right you can have both hot and clean air.

Re: Air filter
What does the air filter help with? Fewer oil changes, less wear?

Re: Air filter
Hopefully less wear. I have also noticed slightly more power on climbs (seat of the pants, no hard data) due to the cooler intake charge.
I personally would not extend the oil change interval just because I was running a filter.

Re: Air filter
I've found this kit from Lang's works just fine. It contact the hogs head so you get some heat. I still get a little condensation on humid days, but no icing. https://www.modeltford.com/item/CARB-FILT.aspx

Re: Air filter
Just wanted to warn Dennis on that clear glass fuel filter, you might want to use something else. I had one on my 68 Cougar and the O rings began to leak and caught my engine on fire. Luckily, I had a halon extinguisher handy and put it out. Just melted some wires. Swapped out that filter pronto.

Re: Air filter
Steve,
you inspired me to sort a 'been meaning to' job.
My '26 Coupe has a Vaporizer so a different design.
I bought a dirt-bike angled filter for about $6 and I also did a bit of sheet metal work.
The tricky bit is a 'dent' on the engine side so that the choke control can operate.
No mods to the car. Doesn't seem to get hot next to the vap.
