We supply American Honda with 13 million oil filters with fiber end caps per year. Toyota factory OE filters have no end caps at all. All AC Delco filters have felt end caps. You have been drinking waaay too much WIX Kool Aid!. Filter efficiency and capacity are all that matters.
Mobil 1 and K+N do not even make filters or own a filter test lab, they buy them from a supplier. Just marketing with their name slapped on it. Fram invented oil filters for pass cars over 75 years ago. look down at the Fram extended guard filter, the writer "cant believe" the quality? It is the best filter in the industry bar none. Yes, its 8 buks but what is YOUR engine worth?
