90 degree oil filter adapter filter

NAPA 1215 is the same micron rating as a comparable 1515, 1068, or 1085. Biggest difference is the filter material. those numbers are longest to shortest. 21 micron on all 3, and a kickass beta ratio of 2/20 = 6/20. To break it down heres how it works. According to the beta ratio chart, the first rating, 2/20, means that the media rating of 2 is 50% efficient at catching particulates down to 6 microns in size. The second rating, 6/20 means that the rating of 6 is 95% efficient at catching particles 20 microns and larger. most industrial filters are a higher micron rating and wix doesnt supply beta ratios for them.
