When I looked up the Puro 20K, it came back with the number of LX3614. The 3614 is the same PN as for the Fram XG3614 I used for many years, which was, IIRC, rated at 99% @ about 20um. Strangely, it's wearing the same gold paint as the Fram XG?? Looks like the20k filter number for my Honda is the same deal. ***? I haven't been following the whole Fram debacle, or any of the others, but wonder if Puro has taken over what was left of Fram?.I just want something equivalent in perforamnce to the XG3614 I was buying. As it turns out, the XG3614 size fits the Escape and both my lawn tractors.
