I will probably be ran out of town for saying this but frams aren't the best but they're adequate. The only real difference is the end caps but those aren't all that important really. Ive used fram my whole life neverbhad a trouble if you want to make the oil changes longer than normal use a better filter otherwise fram is fine
I use Fram's EXTENDED guard filter on my Polaris RZR. It's about $8-9 at Walmart and a LOT better and cheaper than OEM. I'd even use their TOUGH guard filter in a pinch. It is equal to or better than Polaris' OEM one (tough guard).
Here is a pic of the EXTENDED Guard on the RZR. I had to remove some of the mud to show it.
I've used Fram filters in motorcycles and ATVs for years with no issues whatsoever.
I've even taken them apart after three successive oil changes on a KLR650 using the same filter. That's approx. 9000 miles on the filter and it showed no signs of deterioration.
They seem to hold up as well as any other brand I've used including Honda, Kawasaki, Purolator, Kralinator, Wix...
