Well made filter with excellent construction. Gluing is first rate. If this filter had a silicone adbv, it would be a super filter as far as construction is concerned.
Again, good construction. 45 pleats, 7/16" x 1-1/2", very tough paper. Good center support & holes. I don't mind fiber end caps, as they've been proven to work over my years of use, and millions of miles of others use.
This a Champ made filter with Fram design, wonder how old it is. Could be and likely is one from the brief Fram/Champ alliance. The equivalent current Champ made SuperTech 6607 uses metal endcaps and dome bypass.
