I remember seeing them advertised in JC Whitney catalogs when I was just a kid, probably 1966-68. My high school auto shop teacher swore by them and I remember all of us kids snickering when he "changed the toilet paper in his car"!!. I am guessing the fact that toilet paper is used is why a smaller size is not available. Then you would need a dedicated filter element. But it would be easier to fit in the average car if it was smaller.

Mike, there is a smaller size that uses a roll of TP cut in half, same diameter just shorter. The Frantz and filters modeled after it have been around since the mid 50s. People that have used them swear by them, I guess I'm one of them now.
The idea is so simple people are skeptical of it, human nature I guess. I saw one demonstrated in the late 60s, wish I had not been so skeptical and bought one. It would have saved me some money as well as grief over blown engines over the years.
Addressing the size, I have no trouble mounting one under the hood of my 93 K3500, 05 GTO, 08 Vibe, 03 Grand Prix. They can be mounted in a pickup bed, in a trunk. Not sure why the need for a smaller version. It's no longer than the old long oil filters Pontiac used in the early 60s and less than an inch larger in diameter.
Just measured mine and it's 4 1/4 in diameter, 7 inches long without the mounting bracket, and 8 inches long with the mounting bracket.
