RE: {Chrysler 300} 300D/300E/300H Air Filter Elements

K&N has the tall oval filters for the 1957 300s https://www.knfilters.com/chrysler/300/392-v8-carb/1957/

They will make any size filter you want

I had them make a couple shorter ones for my D about 10 years ago

I made a jig that held the tall oval air filter and mounted it to a band saw to cut off about 3/4 of an inch .

then Gary would drop the cut off piece into a mold to put rubber on the other end .

Quiery Has the jig/ band saw for molding the short air filters .

They got at least 75 Wix tall air filters to be cut down .

there is no way they have used all those up .

Give them a call

Put the correct air filter in your oval cleaner !!!!!!!!!!!!!!

I have pictures of a set if anybody would like to see them ..

As our cars age, some maintenance parts are getting harder and harder to get. Air filter elements being one of those. Matt Allyn was showing me how he had a round air filter element squashed to fit his 300H air cleaners. The original Fram number for the 300H is CA163PL. These were also used by the 300D and 300E, as well as other Mopars that used these oval air cleaners.

The round filter he has in there is the Fram CA184. I bought some from Autozone for $5.99 each to try it out. They are pretty easy to squeeze into the oval shape but it is a tight fit. A slightly smaller diameter would work better but I couldn't find anything in my 1970 Fram catalog that would be better. I found it's easier to squeeze it into the lid of the air cleaner first, as it needs to fit all the way into the recess in the top. Then I put the base on and worked the filter to fit in there. Once it's done, it looks pretty good and when bolted to the carb, it's not going anywhere.

Here is a link to pictures.
