AC A212CW Air Filter




The originals had a square mesh then later GM came out with the diamond mesh as shown here which I still own.

They call this a 14" x 3" filter even though it's not really 14" in diameter.



Compare 14" x 3" NAPA Gold 2095 vs ACDelco A212CW

I notice that the black rubber is a hair thicker on the NAPA 2095. Otherwise they've nailed it right on spec.

Also it seems there are more filter webs in the NAPA.
