The pics are intersting. That's the first I've heard of or seen anything regarding a Fram Ultra air filter. Wonder if there's any difference vs the Fram Tough Guard air filters besides changing TGA to XGA and changing the packaging grapics?
Looks like the efficiency rating of the new ST ecore oil filters is using 30 microns as the benchmark rating point consistent with the USCAR36 spec, like the current M1 EP oil filters with the "A" suffix.
Also from the limited pics seen so far these ST oil filters appear to have black ADBV through the limited view available via the ecore combo valve baseplate design. If this is nitrile, I'm especialy curious about the 10K mile rating of these current Champion Laboratories ecore filters. During the fading days of the Frampion relationship, Motorking posted all the filters they manufactured passed their ADBV leakdown testing every time. I surmise that test is only set for freshly manufactured oil filters and not for heat cycle aged ol filtets in / after use. What testing, if any, was done to achieve the advertised 10K mike rating advertised on the packaging of these new production ST ecore oil filters, especialy with respect to simulating end of run conditions, is a question in my mind.
