Hello,
I am the technical director at FRAM. First of all, let me address the failure on here. We did have an issue with a Cummins filter that we addressed immediately when the issue became known. We did buy three engines and changed the design of the filter immediately. No truck owner was out one penny in out of pocket costs. That said, yes, we make oil filters with engineered fiber end caps., So does Filtec (Nissan OE), Mahle (Bentley OE) and others. We have been OE on Honda for 13 years and Subaru for 6 years with this style of filter and never have had an issue with it. We make four styles of filters with the least expensive being the Orange can that is 95.7% efficiency@20 microns, the Tough Guard and Ultra filters at 99%@20 microns.
Nothing WIX makes is better than 85% efficiency at 20 microns, just ask them. Additionally, many brands mentioned in this thread as being "good filters" are designed and built by FRAM filtration. We are OE on Ford, GM, Honda and Subaru. WIX is OE on nothing. All FRAM filters always meet or exceed OE specifications, that is our design mandate. I am more than happy to answer any filtration question by contacting me at
