The thread asking about your first filter purchase, and the looking-back responses, got me to thinking about filter sizes.
When I got started working on cars in the late 1970s, I was mainly working on Mopars from the '60s and '70s. They took these enormous filters which were about 6" tall by 4" in diameter. And the other manufacturers were pretty much the same. Ford filters were about the same size as that, and GM filters were a little shorter but still pretty big. When people said an oil change was four quarts plus one for the filter, that was pretty close to literally true.
Then along came the GM X-body cars with little transverse engines, and these new little oil filters to fit them started popping up in the parts store where I worked. They were itty-bitty by comparison to what we were all used to, and we called them "peanut" filters - does anyone else remember that? We made fun of them; couldn't take them seriously. Customers would balk the first time they bought a filter for their X-car, and some of them would ask if there was a way to retrofit a "normal" filter. And then GM started using them on other engines, and customers didn't like that either, but there was not much to be done about it.
Of course, today that "tiny" filter size is normal and accepted for many if not most passenger car engines. Turns out they work just fine, and if I saw one of those old Mopar filters today it would look freakishly large. Times change.
