Bobcat 6671057 C&P. This was on a Kubota d722 3 cylinder diesel engine that I believe came from a UTV with approximately 500 hours. The filter was quite beat up on the outside and lived a hard life. It was on extremely tight, and the gasket was crushed. It did not leak. I suspect it was on for the entire 500ish hours, but did not see any glitter at all, only carbon. The louver holes (not pictured) were decent size circles. Pleats were even, the one photo with an uneven pleat was me spreading it. The replacement was a Fram Toughguard 7317. I found the specs easily enough, and "its not great not terrible" -Dyatlov. https://shop.kcbobcat.com/products/engine-oil-filter-p-n-6671057
