I'm having a lot of trouble finding the pre-cleaner foam element for my air filter, Briggs & Stratton part number: 393725.

According to the manual, the foam element is part number 5939 and I purchased one here: https://www.ebay.com/itm/283376776427

However, once I got it, it was much to big! Can anyone help me with finding the correct one? I wouldn't worry about it if we wouldn't have so many dry spells in the summer, but it's so dusty that I wouldn't want to run it long without a foam element.

Thanks in advance!

Please post engine numbers, model, type and code.

I'm not sure which numbers are which, but the dealer wrote the engine number as 253707-0159. I also found the numbers 63114961 and Engine number 01 85121910.

I noticed there's more than one engine type included in the manual. Perhaps I was looking at the wrong one and mine doesn't come with a foam element?

IPL does not show a pre-filter for that particular filter.

The filter you posted is for this air cleaner.


Now there is another filter for the following air cleaner that does have a pre-filter.

The 393725 doesn't use a foam wrap, or I have never seen one on that filter. What makes things confusing is that model type list 4 different filters with one being an oil type foam. One being a round cartridge filter with precleaner wrap. And 2 oblong cartridge filters with one using a foam wrap and one without.

So my engine doesn't need one; I'll just have to check it more often and replace as needed. Ya learn something new everyday I guess! Thanks for the information!

That's the one I purchased from Ebay, but it was much too large.

Part number correct, wrong part? That would never happen on anything sold on Fleabay. Go to a good repair shop or dealer for the correct part. Don’t be penny wise, pound foolish.

That is for the 399806 air filter not the 393725 filter. the issue with the fact that it used one of 4 different air filters The 270843 oil foam filter, the 393725 without foam precleaner, the 393957 with 271794 precleaner, and the 399806 with 271962 prefilter.

Sorry I’m bad, old age is catching up on me.
