Original A212CW AC Air Filters

Our 68 L72 Impala has the original A212CW filter, which the original owner saved when he installed the cowl plenum air cleaner. It is square mesh, but the wire goes on a diagonal (45* angle) unlike any NOS ebay filters I have ever seen, early issue or late. It has the screen print just like the one Rixls6 posted, and element is very oiled down. Also, in Hi-Perf Cars mag in 1968 they did a test of the "Street Racers Special" 68 L72 Biscayne and there is a closeup of the engine, showing this same filter with the diagonal wire. The car hadn't been to Motion at this point. The Biscayne the Impala were both built at Tarrytown, NY cars built in Late November, 1967. I'd get a picture on here, but I am away for school.

That's exactly the A212CW element outer screen we expect to see in NCRS '67 Corvette judging - square mesh, oriented diagonally, of solder-dipped round wire. $2K is a common asking price these days for originals. Photo below.

So since everyone is on the subject, exactly which one would be considered correct for a 67 L78 Camaro form a judging point of view?

[Tommy_Mathison]

I have a question for those who have been around longer than I have. Was the oil-saturated filter paper in these elements yellow when they were new or is the yellowing something that comes with age?

[Mr70]

They were slightly yellow when brand new,do to the oil wetted paper and as time wore on they became even yellower, even if never used at all.

[firstgenaddict]

Filter paper is impregnated with formaldehyde and other chemicals which is probably what causes the yellowing, although papers manufactured before the last 15 years used a much more caustic/acidic process to bleach the fiber, which causes yellowing and deterioration. (think old newspapers)
I had 200 tons of waste filter paper bales from a DANA/WIX plant, it would give you a headache just being around it for 30 min. It was almost impossible to get rid of, I sent a load to China, they said NO MORE, I ended up selling it to a company that manufactures roofing felt.
