Whats the difference between these two filters huh? I bought the Fram ultra synthetic filter for my 4.8 Silverado which runs Penn ultra. Should I have just went with the Fram ultra filter. Confused what the difference is between the two !!! Everyones talking about the " ultra" ....but no mention of the " ultra synthetic ".
FRAM ULTRA VS FRAM ULTRA SYNTHETIC

The only difference is the name on the box. Older stock have just Ultra, newer stock have Ultra Synthetic. Exact same filter.
Ulra = Ultra synthetic - 99% efficiency ISO 4548-12 for particles > 20 microns
Xtended Guard = Older stock synthetic filters, basically the same as Ultra but only 97% efficiency under same ISO standards.

The Fram X2 is an even older variant of the Ultra with 94% efficiency.

XG3387A
http://www.framcatalog.com/PartDetail.aspx?b=F&pn=XG3387A
Product Height 3.36"
Product O.D. 2.98"
XG8A
http://www.framcatalog.com/PartDetail.aspx?b=F&pn=XG8A
Product Height 5.14"
Product O.D. 3.8"
XG4967
http://www.framcatalog.com/PartDetail.aspx?b=F&pn=XG4967
Product Height 2.92"
Product O.D. 2.69"
I think what Fram has done is take 3 Ultra filters of different sizes (small, medium and large as shown above), tested them per ISO 4548-12, and came up with an average efficiency and holding capacity.
Nothing wrong with that IMO because it then basically covers their whole range of filters. Purolator only bases their 99.9% @ 20 microns on one filter, their largest being the PL30001.

Yep, that has been talked about quite a few times here. Well, those are much smaller filters (PL14610 being one of them) than the PL30001 that Purolator references in their efficiency spec.
