I hoarded OG FRAM Ultra's and FRAM Titanium's (the latter thanks to former member Rod_Knock, who sent me a pile, since they weren't available in Canada), since they are/were arguably the best filter on the market, an incredibly well balanced combination of flow, capacity and filtration, due to the multiple layers of synthetic media.
If you've been in the oil filter section at all, you are aware that Worst Brands, errr, I mean "First Brands", that acquired both FRAM and Champ, is now bankrupt, but that things went downhill at both companies shortly after the acquisition, including the downgrading of the Ultra, but more significantly, the appearance of considerable QC issues with the filters as they tried to improve margins.
This means that all of the "premium" filters including the Royal Purple and AMSOIL EaO, were affected by this. Sloppy glue jobs, ruffled springs that prevent proper sealing, the elimination of the gasket for the spring we saw on the OG Ultra, louvers in the centre tube that were barely open, or not open at all...etc.
If you are looking for a filter that's along the same style of the OG Ultra (albeit, without the silicone ADBV), probably the closest would be the Fleetguard LF16002, which uses their Stratapore media and is 100% efficient at 24 microns.
I am hopeful that by the time I run out of OG Ultra's that AMSOIL will have partnered with somebody else (hopefully Fleetguard or Donaldson) for the EaO.
