Where do you find a replacement washable K&N air filter A075A4 for the Walker Airsep on my Cummins engines (1997 4788). The K&N web site does not seem to recognize the old number?

I found that even though K&N web site did not recognize the original part number, fisheriessupply.com did, and had in stock sizes from 5" to 9". The 1997 stock size was 7" length 7.5" diameter; I selected the 9" length to provide potentially more air. They had in stock the 5.5" springs as well as the 7.5" springs provided for the 8" or 9" length filter. I went for the new 7.5" springs for the 9" filter and even though they provided 4 springs the 3 springs in the original holes seemed to be adequate.

The reason the K&N site does not recognize the part numbers is that the filters are made by K&N for Walker Airsep. They are proprietary to Walker and not sold under the K&N brand name.
