I recall the filter being heavy also. Almost twice as heavy as the Supertech 9688 Ecore I sent you. This one was $3.99 @ NAPA. The outer box is white and yellow.
Great job giving this girl an autopsy Adam...... thanks.
Looks very good. My plan was to buy a few of these for my upcoming garden tractor oil changes, but current events stopped me from going out and about.
I just buy those orange filters since they can be found where I grocery shop.
