Does that weaved pleat paper element have any benefits over the non weaved pleat.
More media in the same amount of space.
Yeah ..just stretch out the image and you see a much longer filter with straight pleats. Accordion'd on two planes.
I'm waiting for an engineered "spiral twist" media. We already have that when the cartridge filter are just a tad too long
My 2003 Saturn ION had a factory filter with the same pleat design. The filter was made in France.
Every replacement filter I ever used had ordinary pleats, and I have seen them from the U.K, Korea, Bulgaria, Germany, and Mexico.
Also, every other Ecotec factory filter I have ever seen was a Hengst.
It makes me wonder what happened when my car was built. Perhaps there was a shortage of Hengst filters in 2003?
EDIT: and I never saw a France-built Ecotec filter ever again.
