Wix 80%+ of the time. The only fram I will use due to availability issues is the Ultra. Lots of videos on youtube concerning filter comparisons. The high end of each brand are all pretty good. Lower end Frams or just good enough to not void a warranty and nothing more. No such thing as a low quality Wix.
