    Superior Filters

    Posted by Johnno Australia on Aug 9th 2019

    Key to longevity is clean oil. A top performing filter at a reasonable price. I bulk buy from Riff Raff and I live on the other side of the Pacific Ocean.

    Clay does it again, I ordered 4 because the price was so good, can't even believe it. I've been getting these for year and paying almost $40 a piece.

    Posted by Brandon Hoover on Jun 6th 2019

    just like all the other reviews... its gigantic! Its bigger than my head and holds almost a gallon! No idea on if you can run longer oil changes but i did 10,000 with Rotella T5 and didn't run into and "issues"

    Big Filter

    Posted by Beerstalker on Mar 25th 2019

    This filter is humungus, but fits perfectly. It should give extended oil change intervals, and doesn't cost much more than a Motorcraft 1995.

    Best oil filter out there

    Posted by Will S. on Jan 12th 2019

    I can't even believe how riffraff is able to sell these at such a low price for the highest quality filter available. I love the added capacity and improved filtration. My hats off to Clay again on this one.

    Donaldson is the leader in filtration, so why not upgrade? Love these filters, used them for years.
