Hi,
I work at FRAM. Driveworks? Look for made in USA models, those are made by us. The LCR models are not so great unless used for 3k OCI's. The FRAM EG filter is 95.7% efficient@20 microns and rated for 5k OCI's. The Tough Guard is 99% efficient@20 microns and rated for 10k OCI's, FRAM Ultra is 99%@20 microns and rated for 15K OCI's. As far as the end caps? There are now so many filter companies using our design now that the patent has expired you would think it would be a dead issue. Mann and Hummel are using it or just plain glue for end caps, Nissan uses it on OE filters, Toyota is just weaving the ends of the filter media together with no end cap at all. I could provide many more examples but really there is now point, the technology works and others using it is the proof.
