I can not find recent post with list of aftermarket air filters for Twin H air cleaners.
Thanks for any help.

Thank you for the information. I searched as far back as Sept 2013, I must have overlooked the post. Thought the posted comment was more recent than Sept.

Ron, just as an aside, I used to sell to Wix and one day I asked them a question. What is the difference between the NAPA filters you sell to NAPA and the Wix brand name filters you sell? They told me the only thing that was different was that the filter paper. The Wix brand is supposed to have a slightly finer filtering paper than the NAPA filter. Thats it.No other difference. Pricewise I think Wix filters are slightly more expensive than NAPA filters so maybe thats the justification for it.

What's your opinion of K&N ? Are they worth the money & maintenance?

I think they are.  As a plus, they look better.

These part numbers are for the dry Twin-H...is that correct? Is there a dry filter element for the oil bath Twin-H?

Try this:

According to HotRodMan:  STP #SA146  You can use this # to cross reference other brands.

That is correct, bowtie. Add Hasting AF24. They are cheaper then Wix at Summit. WOW! the K&Ns are $38 each vs $7 -$9 for the paper ones. BTY, the Twin H "filters" ( not oil bath) were originally a wire mesh type, which looks like steel wool. They are considerably poor in filtering. I usually install them for AACA judging only.

Thanks guys, that clears that up.

And really, I don't mean to be a snobbish "gotta be original" type of guy, but if you were not aware, the "dry" filters (steel-wool-mesh-type) were originally slated for urban, or city-use.  The oil baths were slated for rural, or country use where dirt/gravel roads were prevalent.  Think about that for a second . . .

That means that a stock oil bath is gonna filter better on the street than any paper filter you can buy.  The downside to the oil baths in stock configuration is that they are messy to maintain, not that they don't filter well enough.

Russ, I agree with the oil bath. But the non oil bath type (drum) used a mesh filter that was to be cleaned in a gasoline mix then replaced dry. You could spray oil on the mesh, but it would collect in the enclosed metal at the bottom of the area where the wing nutted cover is, and drip onto the engine. There entered the paper filters in the mid 50s.

Sorry guys, but I have to disagree with you one the efficiency of the oil bath air cleaners.  Those who are invested in the filter business always told me, the oil bath may filter out nuts and bolts, but dust usually hits the oil, and bounces right on thru the filter housing.  I have no reason to disbelieve this.  I'll take the dry type paper filter every time if I have a choice, and the K & N version is even more superior to oil bath than anything developed beforehand.

Gosh......could it be that they told you that because they were in the biz of selling replacement filter elements? ....bounced off of the oil??? Really? I certainly don't have any empirical data one way or the other but I'd have to call BS on that one.
I'll agree that a dry paper is preferable but I'm not going to throw away my oil bath units any time soon.

I worked on construction equipment for many years. Oil bath was the choice in dusty conditions.

They had to be serviced often, but the dry type would get clogged quickly.

I wouldn't replace an oil bath filter with a dry type on anything.

If you have the paper filter use it. The wire mesh on the twin H setup is not oil bath. They should be replaced with the paper type.

Interesting piece, indeed, with great info on comparisons of several contemporary elements, but............It's apples and oranges when it comes to the comparison of "oil bath" type air filtration and modern "oiled media" types or dry paper. I'm going to guess that a comparison of Fifties (or thereabouts) dry-paper elements to oil bath types would have had very different results than comparing currently available dry paper to those same oil bath types.
Anybody up to funding a test? I'm out!

If you have thought about it...someone else has also.
So a quick google search is all it takes to find an article to support or refute any stance you have.

Guess this thread is a little old... but AutoZone has Fram CA-101's for $5.99

I just ordered one... we'll see! Delivered to the local store, tax brought it to $6.35. Advance and Salvo had no listing at all.
