The Purolator PureOne filters have been having quite a few issues with media ruptures. The Fram Ultra is 99.5% efficient at 20 microns and 80 % @5 microns.
The Fram air filters aren't commonly rated but they are typically top quality.
901Memphis - thanks for your feedback, i will consider Fram Ultra next time. But, during my research for several days studying oil filter comparison articles, i noticed that Fram ULTRA was not mentioned anywhere. This could be because the reviews were several years old and Fram ULTRA was not in production at that time. Check out
this article.
That data was produced by old BITOG member "river_rat". There are lots of old threads about his research and that website is his summary.
Yes, the Fram Ultra hasn't been around too long, but again river_rat might not have went for full synthetic filters in his comparison.
