Volkswagen filters were the ones to beat back then.

I've always wondered if this was the inspiration for K&N air filters. Less restriction = gained HP, and it's reusable after a cleaning.Filtration measured in millimeters rather than microns.
Good question.I'd be curious to see/know how it would test out under today's ISO 4548-12 efficiency standard . . .
It’s actually really amazing to me . . . Just *HOW Many* vehicles were produced - -Even in 1967, people understood the basic logic that better filtration meant cleaner oil and less wear.
Obviously IDK, but my 'speculation' is by today's efficiency test standards, nothing exceptional.Good question.
Was it really that good.....
Kept out the chunks. Makes you wonder what would be found on that screen. Does anyone remember?Volkswagen filters were the ones to beat back then.

The original king of the rock catchers! Along with the "awesome" oil bath air cleaner!Volkswagen filters were the ones to beat back then.

Not much, IIRC... I had 2, my first car-an anemic 1200 CC 40 HP 63 MPH on flat ground top speed '64 Beetle, and a somewhat better '73 Type III fuel injected Squareback. Frequent oil changes were a good idea!Kept out the chunks. Makes you wonder what would be found on that screen. Does anyone remember?

I did many oil changes on these, and I only recall seeing parts of gaskets, seals, and some carbon.Kept out the chunks. Makes you wonder what would be found on that screen. Does anyone remember?
Many of those engines really didn't last very long compared to today. Seemed they were showing signs of lots of wear around the 100K-125K mile mark. Of course all the other things that help reduce engine wear (air filter, oil, materials used for engine parts, manufacturing techniques, etc) were also not as good as they are today.It’s actually really amazing to me . . . Just *HOW Many* vehicles were produced - -
for so many years - - without ANY type of oil filtration *AT ALL* .
Barely even a screen , *if that*
Yes, many needed a "valve job", and also the rest of the vehicle was not built to last either. It was common to have to replace several suspension parts way before that 100k. And maybe a muffler or two.Many of those engines really didn't last very long compared to today. Seemed they were showing signs of lots of wear around the 100K-125K mile mark.

I wish people could understand realities like this. So many young people think "housing is beyond outregeous" and things like that have no concept.Adjusted for inflation,
$3.90 in 1967 is $36.36 in 2024
Spendy… for a filter that’s probably 92% efficient at 40 µm
